Missing null check in ClassLoadingAttributeDefinitions.resolveClassLoader and PermissionMapperDefinitions.createSimplePermissionMapper

[olukas]

If Module.getCallerModule(); on line 54 in ClassLoadingAttributeDefinitions.resolveClassLoader method [1] returns null it will result to NPE on line 57.

The same issue is in PermissionMapperDefinitions.createSimplePermissionMapper. Null can be return on line 203 [2] which will result to NPE on line 207.
