when using java dialect in a accumulate, if there is a binding in the accumulate to a type that is not imported, you get a class cast error instead of the normal unable to resolve

"object.java.lang.ClassCastException: org.drools.compiler.rule.builder.dialect.mvel.MVELAnalysisResult cannot be cast to org.drools.compiler.rule.builder.dialect.java.JavaAnalysisResult"

Please see the following reproducer with three test cases that expect failure.
2 of the tests have the expected failure, one does not.
