> "SWTError: No more handles" error when repeatedly adding a new entry
> --------------------------------------------------------------------
>
> Key: DIRSTUDIO-288
> URL: https://issues.apache.org/jira/browse/DIRSTUDIO-288
> Project: Directory Studio
> Issue Type: Bug
> Components: studio-ldapbrowser
> Affects Versions: 1.1.0
> Environment: Windows XP SP2 all current updates applied
> Eclipse 3.3
> JDK1.5.0_11 with a 512m heap size
> Directory Studio 1.1.0
> Open DS 1.0.0
> Reporter: John Buslawski
> Assignee: Stefan Seelmann
> Priority: Critical
> Fix For: 1.1.0
>
>
> When adding a new entry in Directory Studio, Eclipse sometimes will crash
> with a "SWTError: No more handles" error combined with either an
> OutOfMemoryError, an ArrayIndexOutOfBoundsException, or
> NegativeArraySizeException. The following steps were used to reproduce the
> problem:
> Connect via LDAP Browser to an LDAP server.
> Expand out the tree and pick an group object. In our implementation it would
> look like > dc=initiatesystems,dc=com > ou=Groups > ou=System. Right-click on
> "cn=All Interactions" and select New Entry. ("All Interactions" is a group
> object.)
> In the New Entry dialog select "Create from scratch", click Next.
> On the page, move the object classes from the right side to the left side one
> at a time starting with "account" (the first one).
> Once you have moved about 9 or 10 object classes to the left side, Eclipse
> will just shutdown with no warning.
> The following was in the Eclipse .log file:

> Caused by: java.lang.OutOfMemoryError: Java heap space
> We think the error comes from using createImage() rather than getImage() in
> the getImage() method in the LabelProvider inner class of
> NewEntryObjectclassWizardPage. It appears as though the images keep getting
> recreated with freeing them. For example, the following line:
> BrowserUIPlugin.getDefault().getImageDescriptor(
> BrowserUIConstants.IMG_OCD_ABSTRACT ).createImage();
> should be replaced with:
>
> BrowserUIPlugin.getDefault().getImage( BrowserUIConstants.IMG_OCD_ABSTRACT );
