Groovy Console losing text

I must not be searching with the right keywords to find a JIRA issue for this. If you open a sufficiently long file in the Groovy Swing Console (version 1.5.6, on Win32), random lengths of text may disappear from your file.

Since our projects are currently standardized on Grails 1.0.5, and we’re tied to this version of Groovy, it makes the Groovy Console pretty much unusable to us.

Is there a fix for this?
