Hi Daniel,
X10DT's builder needs a lot of memory, so it would be good to set the heap
space to something like 1G. You don't need to increase the MaxPermSize
beyond 256M. When Eclipse runs out of memory, this sometimes results in
corrupted metadata and strange behavior (this is not specific to X10DT). So
I would recommend making a new workspace from scratch. There is an
indicator you can turn on to monitor your memory usage. Go to Preferences
-> General -> Select "Show heap status". When you see that memory usage is
reaching the limit, it's good to restart Eclipse so that you don't end up
with a corrupted workspace.
Hope this helps,
Mandana
