I use JRebel IDEA Plugin 6.4.3.
In IDEA there is ‘JBoss Server’ run configuration that points to my local JBoss. The JBoss has some modules at %jboss_home%/modules.
If I run the configuration as usual (‘Run’/’Debug’), the JBoss starts and everything works fine. If I run it with JRebel (‘Debug with JRebel’), I get exceptions.
While debugging I found out the cause – files from %jboss_home%/modules/%some_module%/ are not presented in classloader’s class list. But they should be.
