Hi,
Since there was no response to hneemann#866, I'm also opening this PR but can revise it if you want.
Also, this PR is related to hneemann#870, but fixed more flaky tests in
DataFieldConverterTest.javaBy running the following command:
mvn install -DskipTests,mvn edu.illinois:nondex-maven-plugin:1.1.2:nondex -Dtest=de.neemann.digital.core.memory.DataFieldConverterTestThree tests
testMarshalObj,testMarshalObj2,testMarshalObj3inde.neemann.digital.core.memory.DataFieldConverterTestwill fail sometimes.The reason is that method
xStream.toXML()incom.thoughtworks.xstream.XStreamis not deterministic:Xstreamer.toXML(object)method first serializes the object using HashMap and then convert the XML object to string in the order of keys in the HashMap. I fixed the flakiness by checking whether the actual output is in the expected list, which contains all the possible XML combination orders.
