JDK-6809483 - hotspot:::method_entry are not correctly generated for "method()V"
Description
The changes for 6809483 added some callouts to notify dtrace for inlined methods.  in the fill_sync_handler path it's using the regular append call which expects there to be a ciBytecodeStream to get the current bci from but in the fill_sync_handler there is no stream so it crashes.  The code should be yse append_with_bci like the other existing code there.

EVALUATION 7021603: crash in fill_sync_handler with ExtendedDTrace probes Reviewed-by: iveresov The changes for 6809483 added some callouts to notify dtrace for inlined methods. In fill_sync_handler it's using the regular append call which expects there to be a ciBytecodeStream to get the current bci from but once you reach fill_sync_handler there is no stream so it crashes. The code should be use append_with_bci like the other existing code there. Tested with failing tests.
