Description iformanek 2005-06-23 16:00:24 UTC 
Currently, the profiler engine does not support version 50.0 of bytecode. This 
is used in mustang, not by default currently, but only if "-target 1.6" 
compiler option is used.

The 50.0 version will likely be made default for Mustang beta 
(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6283313), we need to 
support it in 1.0. This likely involves work to handle the new StackMapId field 
during instrumentation.

Comment 2 iformanek 2005-08-04 10:47:08 UTC 
Biggeste piece of supporting 50.0 is to adjust the StackMapTable when 
performing instrumentation. Details about this are here:

Comment 3 iformanek 2005-08-08 16:17:24 UTC 
Partially done in M8.
The profiler will instrument 50.0 bytecode without adjusting the stack map 
table, relying on the fallback verifier.

Filing separate issue to cover the remaining work.
