…eadTest If the Thread class is not loaded, frameworks like SootUp or Opal treat the Thread class as a phantom class. Hence, a call like "t.start()" is simply bypassed (since DataFlowScope.EXCLUDE_PHANTOM_CLASSES is used) and not analyzed. However, loading the Thread class results in a failure of the InnerClassWithThreadTest.threadQuery test, if the SootUp or Opal framework is used. This test fails because "Thread.start()" calls the native method "Thread.start0()", which causes the flow to stop. Hence, disable this test for SootUp and Opal. Note: The threadQuery test succeeds in case of the Soot framework because Soot's callgraph has an additional "virtual" edge from "Thread.start()" to "Thread.run()", which keeps the flow alive.
