annotate test/runtime/contended/Basic.java @ 12690:c3bdd186e6cf

fix possible NPE in TruffleCompiler with TraceTruffleCompilation and background compilation enabled. With background compilation, the installed code can already be invalidated when compiledMethod.getCode() is called, in which case it returns null.
