It seems that you have a broken installation.
I see a mixture of incompatible plugins in your Eclipse.
You are using Eclipse 4.2 but your JBoss Tools is partially 3.3 and partially 3.4. You can install JBoss Tools 3.4.1 into Eclipse 4.2 but there is no guaranty that it will work since we did not test JBT 3.4.1 against Eclipse Juno. JBoss Tools 3.3.0 is not compatible with Eclipse Juno at all.
Please intall JBoss Tools 4.0.0. (Alpha 1 is available) if you want to use it with Eclipse Juno.

> I was instructed to try here first on a UI bug in Eclipse. Here a few details:
> When I open my project files in new tabs, files being opened for the first time display completely blank in the code screen. If I double click the tab to maximize, and repeat to minimize, the code then appears normally.
> This happens consistently throughout my workday. I can close a file, open it again and it displays blank (grey background).
> I am attaching the log files and a screenshot showing an exception in org.jboss.tools code.
> -- Configuration Details --
> Product: Eclipse 1.5.0.20120131-1544 (org.eclipse.epp.package.jee.product)
> Installed Features:
>  org.eclipse.cvs 1.3.200.v20120525-1249-7B79FJJAkF7BF7SDL5EAJT
