Which versions of the JDK are supported by JBoss Cache?
JBoss Cache is baselined on Java 5.0 and this is the platform on which JBoss Cache is most thoroughly tested. If, for whatever reason you have to use Java 1.4, you could build a retroweaved version of the core cache library that is Java 1.4 compatible, using the simple instructions on this wiki page on building and running JBoss Cache on Java 1.4. . Note that Red Hat Inc. does not offer commercial support for retroweaved binaries at this stage. Java 6 should work as well, and we haven’t heard of any specific problems of JBoss Cache run under Java 6.
