--------------------------------------------------------------------------------

                 Key: JBRULES-3039
                 URL: https://issues.jboss.org/browse/JBRULES-3039
             Project: Drools
          Issue Type: Bug

          Components: drools-compiler (expert)
    Affects Versions: 5.2.0.M2
            Reporter: Wolfgang Laun
            Assignee: Mark Proctor
             Fix For: 5.2.0.CR1


# no imports here!
global Set<String> nameSet;

causes: 
java.lang.ClassNotFoundException: Unable to find class 'Set<String>'
	at org.drools.base.ClassTypeResolver.resolveType(ClassTypeResolver.java:215)
	at org.drools.compiler.PackageBuilder.mergePackage(PackageBuilder.java:946)

	at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28)

kBuilder.getErrors() returns an irregular error message (no line number, etc.)
 GlobalError: nameSet

Expected: no useless stack dump, proper error message.
