Auto-format causes Java heap overflow

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Open the attached file with the IDE
2. Attempt an auto-format

What is the expected output? What do you see instead?

I expect the code to be formatted.

Instead:

First time, the IDE went into a loop and had to be forced-quit.

Second time:
