Description Douglas Pollock

2004-04-27 12:26:38 EDT

I am seeing this bug in I200404270800.  The debugger hangs and doesn't appear 
to come back (of course, maybe I'm just impatient).  It is reproducible all the 
time for me.  I set a breakpoint within WorkbenchKeyboard.executeCommand, and 
my stack trace does not populate. 
 
When the system is hung, nothing responds.  It is not possible to switch tabs 
in views.  It appears to repaint, and it responds to using the window manager 
to close the workbench window (i.e., click on the "X").  The only way I've 
found to restore sanity is to shutdown, kill the debugging workbench manually, 
and restart Eclipse. 
 
This problem is preventing me from using the debugger in development. 
 
This problem did not occur in previous integration builds, but may be related 
to Bug 55997.

I haven't been able to reproduce this on Mac. What VM are you using? Have you 
tried using a different VM? Would it be possible to attach a thread dump from 
the hung system so that we can get an idea what the debugger is doing?

Sun JDK1.4.2_04 
 
I'll try for a thread dump....

Pressing "Ctrl+Shift+T" seems to restore some sanity, but oddities still 
happen.  The keys work oddly, and keeps locking up. 
 
Looking at the thread dump, this might actually be a problem with SWT.

The "main" thread does seem unhappy. Moving to SWT for comment.
