Chapter 37. Dependencies
37.1. Java Development Kit Dependencies
Seam does not work with JDK™ (Java Development Kit) 1.4, and requires JDK 5 or higher to support annotations and other features. Seam has been thoroughly tested with other JDKs. There are no known issues that are specific to Seam.
37.1.1. Sun's JDK 6 Considerations
The version of JAXB distributed with early versions of JDK 6 was incompatible with Seam, and had to be overridden. The upgrade to JAXB 2.1 (released in JDK 6 Update 4) resolved this issue. When building, testing, or executing, be sure to use this version or higher.
Seam uses Embedded JBoss in its unit and integration testing. When using Embedded JBoss with JDK 6, you must set the following JVM argument:
-Dsun.lang.ClassLoader.allowArraySyntax=true
Seam's internal build system sets this by default when it executes Seam's test suite, but you must set this value manually when using Embedded JBoss.
