GWT UIbinder auto complete is very slow

I am working on GWT2.3 with Eclipse Ganymede version 3.4. While working with UIBinder, the auto complete feature (suggestions) is very slow.

I am not getting what 开发者_运维技巧to do in this situation. I need to add some plugins or files. It too slow to work.

Comment out the DOCTYPE as a work around. It resolved the issue for me.

There's a discussion about this issue here:

And the solution posted by cave (comment #27) seems to be the easiest solution.
