Subject [jira] Commented: (DIRSTUDIO-288) "SWTError: No more handles" error when repeatedly adding a new entry
Date Mon, 03 Mar 2008 23:30:53 GMT

    [ https://issues.apache.org/jira/browse/DIRSTUDIO-288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12574788#action_12574788
] 

John Buslawski commented on DIRSTUDIO-288:
------------------------------------------

The description should have read as follows. Changes are in CAPS and bounded on each side
with '***' (asterisk):

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 ***LEFT*** side to the ***RIGHT*** side one
at a time starting with "account" (the first one).

Once you have moved about 9 or 10 object classes to the ***RIGHT*** side, Eclipse will just
shutdown with no warning. 



Sorry for the confusion.

> 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.

> 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 );
