The issue seems to be platform-dependent, as I'm not getting any exceptions in a
gtk.linux.x86 build.
Some debugging revealed that StyledTextRenderer's internal data structures assume a
different number of lines present than what content.getLineCount() returns in
calculateClientArea(); these two values are usually kept in sync with the use of
TextChangeListeners. I think that because of TransformedDocument's lazy update
mechanism, new state can be returned to the renderer without firing a corresponding text
change event first.

I am seeing this issue again under Eclipse Indigo, Drools 5.4 stable. Any DSLR file using
a DSL causes this, even for a trivial DSL file and DSLR file.

David Goldstein commented on JBIDE-12070:
-----------------------------------------
I think the bug was introduced in the move to Eclipse Indigo. I took some code developed
in 5.1 and 5.2 and brought it into Helios SR2 that was originally using 5.2.1 plugins for
Eclipse after getting the bug seen in 5.4. In Helios version opens the DSL Rule Editor
for DSLR files. However, trying to go to the "DRL Viewer" tab fails and removes
the tab from the editing pane. I do not see a *.log file (other than install.log) under
the Eclipse installation or in the workspace and no relevant log file seems to be in the
DROOLS directory.

The issue seems to be platform-dependent, as I'm not getting any exceptions in a
gtk.linux.x86 build.
Some debugging revealed that StyledTextRenderer's internal data structures assume a
different number of lines present than what content.getLineCount() returns in
calculateClientArea(); these two values are usually kept in sync with the use of
TextChangeListeners. I think that because of TransformedDocument's lazy update
mechanism, new state can be returned to the renderer without firing a corresponding text
change event first.

Vijay Kiran Duvvuri commented on JBIDE-12070:
---------------------------------------------
My Eclipse installation is having the same issue (Mac Java6 and 32bit).
Here's a workaround I found - open the rules file in another editor, edit and save it.
Return to eclipse and press F5 to refresh the resource. This at least makes the file
editable.

The issue seems to be platform-dependent, as I'm not getting any exceptions in a
gtk.linux.x86 build.
Some debugging revealed that StyledTextRenderer's internal data structures assume a
different number of lines present than what content.getLineCount() returns in
calculateClientArea(); these two values are usually kept in sync with the use of
TextChangeListeners. I think that because of TransformedDocument's lazy update
mechanism, new state can be returned to the renderer without firing a corresponding text
change event first.
