I'm glad you were able to fix this problem. If you think the problem is caused by STS, and you think you can reproduce it. It may be worth raising a bug on the issue tracker (https://issuetracker.springsource.com/browse/STS). If we are able to figure out what caused the problem in the first place, we may be able to do something about it and save some other people a bunch of hassle in the future.
Trying to reproduce and document the steps is some work on your behalf, so if you rather just not do that and get on with your actual work instead, I understand. So don't feel pressured :-)
