AllocationCodeBlobTest.java fails because we don't expect an allocation in the code cache if "-XX:CompileCommand=compileonly,null::*" is set:

java.lang.RuntimeException: free shouldn't increase memory usage: 4768896 <= 4764672 (assert failed: 4768896 <= 4764672)

The problem is, that with Indify String Concatenation (JDK-8148483), additional invokedynamic instructions are resolved, triggering method handle intrinsic creation:

538 33 n 0 java.lang.invoke.MethodHandle::linkToStatic(JJL)L (native) (static)
539 34 n 0 java.lang.invoke.MethodHandle::invokeBasic(JJ)L (native)
