5. Known Issues

BZ#1025057 - SSLProxyMachineCertificateFile doesn't support PKCS#8 key format

In JBoss Web Server, when a PKCS#8 key generated by OpenSSL is used, JBoss Web Server displays the following error and then terminates: 
incomplete client cert configured for SSL proxy (missing or encrypted private key?)

The PKCS#8 format is not supported by mod_ssl, as mod_ssl uses different functions when loading the proxy key pair.

This is a known issue in JBoss Web Server 3.0. As a workaround, convert from PKCS#8 to the raw PEM encoding of the RSA key and use "openssl pkcs8".
BZ#1157769 - JWS: VirtualHosts share pointer to mod_proxy configuration, results in: CreateBalancers behave the same with option 0 or 2

The directive CreateBalancers with the option 0 or 2 creates the balancers on all Apache HTTP Server virtual hosts.

When using option 2, it is expected that the balancers should be created on the main server only, and not on the virtual hosts.

The cause of this issue is under investigation, and is expected to be resolved in a future release.
BZ#1155686 - Tomcat7 sessionsList.jsp does not work

This release of JBoss Web Server contains an issue with sessionsList.jsp in Tomcat 7 and 8. An error similar to the following is thrown during compile: 
An error occurred at line: [18] in the generated java file: [/usr/share/tomcat7/work/Catalina/localhost/manager/org/apache/jsp/WEB_002dINF/jsp/sessionsList_jsp.java]
Only a type can be imported. org.apache.catalina.ha.session.DeltaSession resolves to a package

An error occurred at line: 109 in the jsp file: /WEB-INF/jsp/sessionsList.jsp
DeltaSession cannot be resolved to a type
Copy to Clipboard Toggle word wrap

This error occurs because sessionsList.jsp has a dependency on the DeltaSession HA class.

This issue is expected to be resolved in a future release of JBoss Web Server.
BZ#1100599 - Tomcat7 - catalina.out contains warning and errors (after shutdown)

When using JBoss Web Server 3 on Microsoft Windows, starting and then stopping Tomcat7 results in warnings and errors being unexpectedly displayed after Tomcat7 has shut down.

The web application [/docs] initiates a thread named [SeedGenerator Thread] but does not stop the thread when it shuts down. As a result, the errors and warnings continue to appear after Tomcat7 shuts down.

This is a known issue in JBoss Web Server 3 and there is currently no workaround for this problem.
BZ#822250 - Tomcat6 mod_cluster config file (JON)

In JBoss Web Server, a mod_cluster config file error is displayed on the Inventory Connections screen even after configuring the file.

This is a known issue in JBoss Web Server 3 and there is currently no workaround for this problem.
BZ#1201269 - Tomcat 7 datasources are not discovered if defined in server.xml file

This release of JBoss Web Server carries a bug that prevents Tomcat 7 datasources from being discovered if they are defined in the server.xml file.

A workaround to this issue is to define the datasources in the context.xml file.
BZ#1086412 - SSLFIPS option does not operate the same as RHEL httpd

In JBoss Web Server, the SSLFIPS option does not operate as expected.

This is a known issue in JBoss Web Server 3 and there is currently no workaround for this problem.
BZ#1116863 - [rpm] hibernate extra source jars

In JBoss Web Server 3.0, some source files are included in the Hibernate RPM distribution that are not present in the Hibernate ZIP distribution.

This is a known issue and there is currently no workaround for this problem.
JWS-106 - Tomcat7: Unable to compile selinux policies

Compiling targeted tomcat8 module
/usr/bin/checkmodule:  loading policy configuration from tmp/tomcat8.tmp

The cause of this issue is currently under investigation.
JWS-99 - httpd apxs utility needs EWS_HOME var. set

To be able to properly run the Apache Extension Tool (apxs) with Apache HTTP Server in JBoss Web Server 3, the EWS_HOME environment variable needs to be set to the JBoss Web Server installation directory.
JWS-93 - Windows: set DefaultRuntimeDir

In this release of JBoss Web Server on Microsoft Windows, the Apache HTTP Server directive DefaultRuntimeDir does not point to the installation directory.

As a result, the mod_auth_digest shm files are created in logs directory.

This issue is expected to be fixed in a future update.
JWS-86 - Upgrading Tomcat plugin, metric names not updated

When upgrading a RHQ 4.5 installation to 4.6, the Tomcat plugin may not be properly updated.

In this situation the following exception is thrown: 
 java.lang.IllegalArgumentException: The property [name] marked as required in the configuration definition of [Tomcat Connector] has no attribute 'default'
Copy to Clipboard Toggle word wrap

The cause of this issue is currently under investigation.
JWS-85 - Problem to start tomcat with a user whose group has a name different to the user

The Tomcat init scripts are not designed to be run by a user with a name that does not correspond to an existing group.

In this situation, the Tomcat processes are not able to be stopped with the provided scripts, as well as other operational issues regarding the CATALINA_PID file.

To workaround this issue, please follow the configuration instructions in the JBoss Web Server 3 Installation Guide, and create a tomcat user that belongs to a tomcat group.
JWS-84 - Tomcat8: Backport Add option to disable log rotation in FileHandler.

Tomcat 8 in JBoss Web Server 3 does not currently have the ability to disable log rotation in 'FileHandler`.

This issue will be fixed in a future update.
JWS-79 - mod_cluster-container-jbossweb.jar in RPM installation

mod_cluster-container-jbossweb.jar and mod_cluster-container-jbossweb-sources.jar shipped in mod_cluster are not supported by JBoss Web Server 3.

If you include /usr/share/java in your CLASSPATH, these jars may prevent mod_cluster from registering to the load balancer.

Please remove these two jars if you want to include /usr/share/java in your CLASSPATH.
JWS-67 - Windows: Tomcat8 WebDAV move operation fails

Attempting to execute a MOVE operation in Tomcat 8 on Microsoft Windows returns a HTTP 500 error. An error similar to the following is added to the access_log: 
127.0.0.1 - tomcat [16/Apr/2015:02:58:43 -0700] "MOVE /webdavapp/webdav/hello.txt HTTP/1.1" 500 1040

This issue is currently under investigation.
JWS-61 - Tomcat7/8 breaks session stickyness with ;jsessionid= followed by /

If a / is included after a jsessionid in a URL, this may result in Tomcat 7 and Tomcat 8 failing to maintain the client session. In this situation, Tomcat fails to understand the jsessionid string and creates a new jsessionid.

This issue is currently under investigation.
JWS-54 - JON Tomcat8: Not discovered default web app config values

It has been reported that when deploying some applications through the JON interface to Tomcat 8, the following error is encountered: 
The following configuration properties have invalid values: [Allow Linking, Anti Jar Locking, Caching Allowed, Cache TTL, Cache Max Size, Save Config]. The values must be corrected before the configuration can be saved.
Copy to Clipboard Toggle word wrap

This error presents because the default values of the listed properties are not discovered in Tomcat 8. This issue prevents the configuration from being saved until valid settings are entered for each property.

This issue is under investigation.
JWS-48 - JON httpd plugin for mod_bmx not provided yet

A Red Hat JBoss Operations Network plugin for Apache HTTP Server in JBoss Web Server 3 is not included in the general availability (GA) release. A new plugin that uses mod_bmx will be published after the release of JBoss Web Server 3.
JWS-27 - Windows: private key before PEM certificate causes Segfault

On Microsoft Windows, sending a request via a mod_proxy reverse proxy to a https backend results in a segfault. Using gdb shows that having the private key before the certificate in SSLProxyMachineCertificateFile triggers the segfault.

This is a known issue in JBoss Web Server 3 and is currently under investigation.
JWS-24 - Windows: mod_jk does not work with ipv6

In this release of JBoss Web Server, mod_jk does not work with IPv6 addresses, and may create logs in mod_jk.log similar to the following: 
[error] ajp_validate::jk_ajp_common.c (2748): worker worker1 can't resolve tomcat address ::1
[error] ajp_validate::jk_ajp_common.c (2748): worker worker2 can't resolve tomcat address ::1

JWS-6 - hibernate c3p0 mchange-commons-java raises error on IBMJDK

If using mchange-commons-java in Hibernate c3p0 on an IBM JDK, a java.lang.ClassNotFoundException: org.slf4j.ILoggerFactory error may be thrown.

You can work around this issue by setting the following property in your application: 
System.setProperty("com.mchange.v2.log.MLog", "com.mchange.v2.log.jdk14logging.Jdk14MLog");
