Raffael,
Assuming it is not a classpath problem, I don't know what is
happening by your stack trace. Can you provide more info, or maybe a
self contained test case?
It would be good to know:
1. What jbrules version are you using?
2. What environment? Stand alone application, JEE application, what
container?
We fixed an issue related to security in the version 3.0.5 that was
release today, that could potentially cause that. So if you are not
using 3.0.5, it would be good to test with it.

There are two rules which cause this error:
rule "java:populate:sources"
when
unit: CompilationUnit()
not Path(role==("java:sources:"+unit.getName()))
then
assert(new
Path(unit.getSourcePath(), "java:sources:"+unit.getName()));
end
and
rule "java:populate:sources"
when
unit: CompilationUnit()
not Path(role==("java:sources:"+unit.getName()))
then
assert(new
Path(unit.getSourcePath(), "java:sources:"+unit.getName()));
end
Any ideas?
TIA,
Raffi
