Subject [jira] Commented: (HARMONY-1891) [drlvm][jvmti] VM hangs after multiple Single Step event enabling
Date Tue, 17 Oct 2006 10:19:36 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1891?page=comments#action_12442857 ] 
            
Gregory Shimansky commented on HARMONY-1891:
--------------------------------------------

AFAIK there is no need to set a breakpoint in a thread which is started inside of jvmti_send_thread_start_end_event
function.

This function is called when no java code in the new thread is executed yet, so this function
just sets single step state for this thread. When this thread will be ran, calling the first
java method will set a breakpoint on the first bytecode if this mehod.

You can add the above paragraph as a comment in place of the code which you've added.

> VM hands if Single Step event is enabled several times (and not disabled). It happens
due to before enabling single step VM suspend all thread and if Single Step is already enabled
VM doesn't resume threads.
