When the JVM was built without AOT we observed the following test failure (note that AOT is currently unsupported on some platforms like e.g. PPC64):

TestInstanceKlassSize was failing because of wrong size computation.
The problem is that the implementations in the following files don't fit together:

src/hotspot/share/oops/instanceKlass.cpp:
bool InstanceKlass::should_store_fingerprint(bool is_hidden_or_anonymous)
bool InstanceKlass::has_stored_fingerprint()
They always return false when built without AOT.

src/jdk.hotspot.agent/share/classes/sun/jvm/hotspot/oops/InstanceKlass.java:
public static boolean shouldStoreFingerprint()
public boolean hasStoredFingerprint()
They return true in some cases regardless of whether JVM was built without AOT or not.
