Chapter 5. Fixed issues

In Eclipse Vert.x 3.9.5, vertx-rx-java and vertx-rx-java2 modules were marked as optional dependencies in the POM files. However, by default, the Eclipse Vert.x JUnit5 extension code loaded the Rx versions of Vertx and WebClient classes. Since these dependencies were not available, exceptions were thrown.

This issue has been fixed in Eclipse Vert.x 3.9.6. The RxJava1 and RxJava2 dependencies have been added by default in the POM file.

In previous releases of Eclipse Vert.x, when building a project that includes the vertx-kafka-client artifact, Maven generated the following warning, potentially causing the build to fail:

The POM for org.scala-lang:scala-compiler:jar:${starr.version} is missing, no dependency information available

The POM for org.scala-lang:scala-compiler:jar:${starr.version} is missing, no dependency information available

This issue is resolved in the Eclipse Vert.x 3.9.6 release and no longer occurs.

In previous releases of Eclipse Vert.x, a messageHandler attached to an AmqpReceiver instance that was set to print a message received from a Sender instance located on the same address to standard output would fail to print the message to the log despite having received it. The issue resulted from using a deprecated createReceiver method to initialize the AmqpReceiver instance. The deprecated method is removed from the vertx-amqp-client module in the Eclipse Vert.x 3.9.6 release and the issue no longer occurs.
