NPE in JBossClassLoaderHandler#findClasspathOrder

[arthware]

In our scenario we get a NullPointerException in JBossClassLoaderHandler#findClasspathOrder

The moduleMap is null in our case, leading to an NPE in the next line, when accessing the entrySet.

classgraph/src/main/java/nonapi/io/github/classgraph/classloaderhandler/JBossClassLoaderHandler.java

Lines 213 to 215 in f874380

	final Map<Object, Object> moduleMap = (Map<Object, Object>) ReflectionUtils.getFieldVal(false,
	callerModuleLoader, "moduleMap");
	for (final Entry<Object, Object> ent : moduleMap.entrySet()) {

I was able to fix this with a simple null check. The scan returns the expected results.

Before:
for (final Entry<Object, Object> ent : moduleMap.entrySet() ) {

After:
Set<Entry<Object, Object>> moduleMapEntries = moduleMap != null ? moduleMap.entrySet() : Collections.emptySet(); for (final Entry<Object, Object> ent : moduleMapEntries) {

Fixed via #652. Thank you!

Thank you for merging and your efforts!

@lukehutch any chance to get a release pushed out in the next two weeks? That'd be awesome. Thank you very much!

[lukehutch]

Yes, I'm sorry for the delay. I will do it in a few hours once my current flight lands!

OK, I was able to push out version 4.8.140 with this fix. I probably should have just done this after merging. Thanks again for your fix!
