diff src/annotations/gov/nasa/jpf/annotation/NoJPFExecution.java @ 17:e15b03204dc7
added a @NoJPFExecution annotation, which sets a NoJPFExec system attr on marked
methods during class load time, which gets checked by ThreadInfo.enter(). Useful
to flag methods which have to be intercepted/cut off when executing classes
under JPF that can also be used outside. Especially useful to avoid the
recursive JPF problem that can be caused by tests (which mix classpath and
native_classpath). This currently throws a JPFException, but we could also turn
this into a AssertionError in the SUT so that we get the SUT stack trace
