All,
After going through and plugging all my own leaks when creating SWT
resources, I am still getting the dreaded no more handles error in my
GEF-based plugin. I am using 2.1.2 and have updated the draw2d jar that
Pratik posted to bug 53632. I have this error happening for several
users on several different machines and configurations.
In the last comment to this bug Randy mentions that this doesn't happen
in 3.0 because there is better error handling. Is it possible to get
these into the 2.1.x stream?
Also, I noticed that there are several open bugs on different causes of
the "No more handles" error. What is the best way to determine which
effect I am seeing? Obviously if I see draw2d in the stack, I know that
it is this one.
Thanks,
Phil

You should report the conditions which cause this problem on the bugzilla.
Version 2.1.3 has been completed and tested by various GEF clients. There
are no plans for a 2.1.4 at this point. That doesn't mean that it won't
happen, but it is not scheduled.
You can try taking the code from HEAD and merging it into your own 2.1.x
version of the draw2d plug-in. The affected class is
BufferedGraphicsSource.

I had the same problem but usually it was a loop that never stopped. Also,
I don't know what to do about that, but the paintFigure method is called
way too often and so eats all the ressources. So far, the only solution I
found was to put a sleep but it sure ain't great.

Hello,
I recently downloaded the Clay Database Modelling tool from Azzurri
(www.azzurri.jp). Once I installed this plugin into both Eclipse 2.1.3
and WSAD 5.1.1 and tried to create a new database model I got the "No
more handles" exception.
Since I tried this at the office, I use my regular userid. I then
tried to do the same with my Windows Administrator userid and
strangefully enough, everything worked just fine.
After I created a new database model and left the GEF based model
editor opened when closing Eclipse/WSAD, I was no longer able to
restart Eclipse/WSAD with my regular userid because of the No handles
exception.
So it looks like the code that is executed could require some special
access rights. If you work on your private PC you normally have all
the rights, but on a corporate PC, based on your corporate security
setting and constraints, your userid might not have all the necessary
access rights.
I have not been able to recreate the problem with my Administrator
user, but with my normal user I get the problem each and every time.
Maybe this can help tracking down what is happening.
Alex
PS: I'll be on holiday 'til next Thursday. So if I might not be able
to reply to a follow up question. I will do so on Thursday of at the
latest of Friday.
