javadoc says:<br>
"An enumeration of <code><a

objects for the resource. If no resources could be found, the
enumeration will be empty. "<br>
<br>
So that seems a reasonable request. I'll get it updated.<br>

Clarification to this - it does also happen when we run our
server. So this is preventing us from upgrading to 5.2

<div>I have traced the problem to <span
style="color: rgb(29, 0, 147); font-family:
Monaco; font-size: 11px;">org.drools.rule.</span><span
style="color: rgb(29, 0, 147); font-family:
Monaco; font-size: 11px;">JavaDialectRuntimeData$PackageClassLoader.getResources</span>.
This returns null whereas AspectJ expects it to
at least return an empty enumeration - hence the
NPE. Interestingly the problem does not occur
when running our server, however we can't
upgrade unless our unit tests pass and we can't
easily turn off aspectj for these.</div>
