Hi all,

could you please review the fix which improves and refactors DoPrivAccompliceTest.java test?
the test had several issues:
 - it did not fail if the java spawned by JavaToolUtils::runJava exists w/ non-zero exit code
 - negative test case was not covered, i.e. the test did not check that if privileges are not granted to the right jar-file an exception is thrown
 - the test created files inside test.classes, which might interfere w/ other tests
 - the test uses JavaToolUtils testlibrary class to create a jar, start a jvm, which duplicates functionality of the common testlibrary and will be removed by 8180898[1]
