StackOverflowError while Refactoring

Question

I'm trying to refactor a package name (pretty near the root of the project hierarchy), and I'm getting the following error (flash builder 4):

A fatal error occurred while performing the refactoring

An unexpected exception occurred while creating a change object.  See the error log for more details.

The log file looks like this....

Any ideas what is wrong...and what I can do to fix it ? I queried google for it, and didn't turn up anything useful with the parameters I tried.

Answer 1

You can try to Restart Eclipse. Oddly that fixes a number of issues in Eclipse that happen all of a sudden with no normal explanation.

Answer 2

Increase the thread size of the JVM you run your IDE in?

I believe in Eclipse you could do it by adding -Xss with some value to eclipse.ini within your Eclipse installation. The setting is a JVM setting so should be added in the -vmargs section, it might be next to -Xmx which is there by default.
