Hello,

since I upgraded from jboss 4.0.3SP1 to 4.0.4 I'm having problems
using the quartz scheduler. If I try to load a Javabean within
a scheduled job:

InitialContext ctx = new InitialContext();
Test t = (Test) ctx.lookup("Test/remote");

the following exception gets thrown:

14:29:55,518 ERROR [ErrorLogger] Job (XX.X threw an exception.

Is this a problem in jobss or quartz?
