md5Hash results with line endings \r\n on MaterializedLambda tests on Windows

Several testes are failing on org.drools.modelcompiler.util.lambdareplace package due the md5Hash function called on className method on classes which extend MatarializedLamda class because Windows consider \r\n as line endings. So the md5Hash results different hashcodes than the expected on assertions.

If there is any customer's use case related to this usage, I believe that the software should deal with the compatibility between different operating systems.
If the hash isn't stored and computed only on runtime, the test approch might be changed to compute the hash on the same way it is in production instead of loading it from stored files. Or a different solution might stood up.

Failing tests:

• MaterializedLambdaPredicateTest.createClassWithOneParameter
• MaterializedLambdaPredicateTest.createClassWithTwoParameters
• MaterializedLambdaExtractorTest.createExtractor
• MaterializedLambdaConsequenceTest.createConsequence
• ExecModelLambdaPostProcessorTest.convertFlowLambdaDoNotConvertConsequenceWhenDrools
• ExecModelLambdaPostProcessorTest.convertPatternLambda

If the \r is removed when calling md5Hash function, all testes pass. See the attachment [materialized_lambda_hash.patch].
