JDK-6294277 - java -Xdebug crashes on SourceDebugExtension attribute larger than 64K
Description
from Java licensee:

"...backport did not remove the code in instanceKlassKlass.cpp that processess the _source_debug_extension field as an OOP.  This results in a fatal error during garbage collection."

Initial review of code supports this conclusion. Need to fix this before regression makes it into released product. Note issue does NOT impact other versions of Java, only 6.
