I have discovered that I have to have my Java Agent configured in the .cfg file for it to happen:
[JavaOptions] java-option=-javaagent:$APPDIR\libs\MyAgent.jar The agent is needed in my real app only to get an instance of the Instrumentation interface. In my test code, where I have reproduced this, it is never used. My test app just takes a URL and fetches it via a HttpURLConnection with setInstanceFollowRedirects(false) so I can capture the new location. If you are still having trouble reproducing I will have the code cleaned up for the bug report soon...
