I have trouble to create a ExtJS project with Eclipse (Helios) on OS-X. I have no issue with any other PHP/Javascript projects. Eclipse will simply stuck in "Building workspace", suck up most of the CPU time and eventually die out with java heap space.

I have tried the following:
- modified eclipse.ini file to crank up memory, try both 512M and 1024M with same result
- clean up Eclipse workspace with "-clean" and "-initialize"
- remove .metadata data to start from fresh
- download latest Eclipse IDE

It seems Eclipse is stuck in some recursive operations. Any insight. What other IDEs will you recommend as I am out of idea with Eclipse....
