Description

Crash on regular expression find and replace for multiple spaces.

Steps to Reproduce

1. Working on .HTML files, tried several
2. Find/replace for regex: "\s\s+" and replace with nothing
3. cursor changes to the spinning ball and the Developer console shows a thrown exception (can't save the console - doesn't seem to work when I select "save as" because of application state, I believe.

Expected behavior: [What you expected to happen]
Replace multiple white spaces without application hanging.

Actual behavior: [What actually happened]

The replacement happens, but the application hangs with a spinning cursor. Need to exit and restart. Debug console shows:

"Exception in 'doReplaceAll' listener
