Eclipse – Problems saving workspace

eclipse

Periodically (during autosave) and at close i get:

Problems saving workspace

(X) Problems occurred while trying to save the state of the workbench.

Details >>
  Could not write metadata for '/projectname'. 
  encoded string too long: 123456 bytes

Can't find a reason or solution for this using the usual means. Any ideas how to fix?
THis is using eclipse 3.4 (Ganymede)

Best Solution

It should relate to a bug in DataOuputStream that it cannot writeUTF with longer then 65535 utflen.

If I were you, I will try to find a way to reduce the data size, and I will submit bug report to Eclipse and JRE.
