When saving my first project in my documents folder on windows 7 the application became non-responsive for a few seconds and then threw a java.langRuntimeException: Unexpected code path
The dialog this error message was presented in had an OK button, but clicking on either the OK button or the close window X did nothing, I then had to quit the application via task manager
the error message is related to a bug in the internal database engine in Jet Profiler, H2 database. It occurs very rarely (you are the first to report this), but unfortunately, it can cause the saved project to become corrupt.
We will upgrade the h2 database version in the next Jet Profiler release. This will hopefully resolve the issue.
