is vmSymbols::java_lang_InvalidClassException() valid?

[David Holmes - Sun Microsystems]

Hi Christian,

The other places in the hotspot code where it is thrown are legacy methods:

// JVM_AllocateNewObject and JVM_AllocateNewArray are unused as of 1.4

and so never called. (Hotspot sill has a bit of legacy baggage here and 
there.)

The unsafe code however calls getBaseAndScale via arrayBaseOffset and 
arrayIndexScale, which appear to be used within Unsafe.java itself. I 
didn't have time to see if those parts of Unsafe are themselves no 
longer called.

I even tried a quick search of 1.3 and couldn't find 
java.lang.InvalidClassException. It would have to have been a non-public 
class, possibly a LinkageError subclass, to disappear.

Interesting. Perhaps the library folk would know the history here.

Cheers,
David Holmes
