Hi,
Does anybody know what the size returned by
java.lang.instrument.Instrumentation.getObjectSize when passed a Class
instance actually means? It is different for various Class instances
(contains static fields of various classes?). It's also quite big (520
bytes for Object.class on 64bit JVM without compressed OOPS). If I
remove some instance fields from java.lang.Class the reported size stays
the same.
Regards, Peter
