Kurt Stam commented on JBRULES-596:
-----------------------------------

This is still an issue in 4.0MR2 as well. By now most projects use jdk5, JBossESB certainly is. So the workaround is now pretty much obsolete. It'd be nice to have this fixed before 4.0 goes GA.

> If a person's Eclipse is set to use jdk5 as the default, it can cause the plugin to not work. The error in the problems summary in eclipse says "unsupported major.minor version". The solution is to set the rule project to use jdk1.4.
> right click on the project
> select properties
> select java compiler
> change setting to jdk1.4
> another potential workaround is to set eclipse to use jdk1.4 as the default.
