I just upgraded from indigo to juno. Now if eclipse generates the index for my workspace it runs for a long time and than report a java out of memory error.
It will work if I remove all the include paths. Especially the Qt includes seem to provide a problem. Ok, these are a lot of files, so I try to increase the java memory, by starting eclipse with -vmargs -Xmx1024m arguments. But this does not help either.
