Eclipse interruptions under Mac OS 10.7 Lion

I upgraded to Mac OS 10.7 Lion a while ago, and although Eclipse (Eclipse Java EE IDE for Web Developers, Version: Helios Service Release 2) works fine two things go very slow:

  • Creating a new project used to take a few seconds, now it takes about 1.5 minutes.
  • Every now and then when saving my classes everything stops, and the spinning wait cursor appears for about 1 minute. The Activity monitor labels Eclipse as "not responding" during that time.

I have the latest Eclipse update. Does anybody know what could cause this behavior?

Thanks, Mike


Try cleaning Eclipse, run this from the command line, in the directory where Eclipse is installed:

./eclipse -clean -vmargs -XstartOnFirstThread

Try adding more heap space. In your eclipse.ini file in the installation increase the max heap (-Xmx). It's likely you are near the limit of the memory, so it's excessively garbage collecting.
