Description Jan Chalupa 2006-12-11 21:00:23 UTC 
[2006-12-08 daily]

Tried to open and edit relatively big .js files:

http://prototype.conio.net/dist/prototype-1.4.0.js
http://openrico.org/rico/download_file/1.1.2/rico.js

The performance was gradually getting worse until the IDE became almost 
unusable (will attach a thread-dump). It also seems that the JavaScript 
support needs a lot of memory and is reluctant to return it back. It doesn't 
take long to use the full heap when trying to edit various .js files.

I have fixed this issue today.
Verify it in next build, please.

I'm no longer able to reproduce the problem with the 2006-12-11 daily. The JS
support still seems to consume memory a little too fast, but the performance
doesn't seem to be degrading as before.
