Aaron, Nikolaos, Thanks for your responses. I have learnt a lot from Aaron's request to reproduce the error in a simple, self contained example, and have found out that using a view helper in my page (A concept i learnt from Freddy's book) is causing the problem that i have.
When stripes is handling the view helper, a RequestComplete lifecycle stage event is triggered once the view helper has been handled. However, the jsp is not fully handled at that stage yet: in my jsp, i'm still doing more stuff after the inclusion of this view helper. This "early" RequestComplete causes Stripersist to clean up, but i still need to fetch stuff from the database. This is demonstrated in the example i have made, which can be downloaded at: http://wikisend.com/download/598940/example.zip It uses gradle. The gradle wrapper is included in case you don't have gradle. Useful commands (run from project root folder) gradlew eclipse - generates eclipse files, for easy import. gradlew jettyRun - deploys the project in an embedded jetty server. Point browser to localhost:8080 :) Removing the view helper, or pasting the view helper below the results table in the jsp "fixes" the problem. I am not sure if it's intended for Stripes to fire a RequestComplete event when it's still processing the jsp. If this is indeed intended behaviour, then either i have to just remove my view helper, or the Stripersist interceptor has to somehow track if it can expect more RequestComplete events this thread, so it can keep around the entitymanager(s) a bit longer. Note that in stripes 1.5.3, the Lifecycle from the view helper seems to wait with the RequestComplete event until the jsp is done processing. I currently have resorted to removing my view helper, which results in my pages having a single RequestInit and -Complete cycle again :) I hope the included example makes things a bit more clear.

We are using it directly and in unit tests and no issues. One thing that helped me solve issues I thought were related to Stripersist was debugging with the Stripersist source code and stepping through the code. Here is what I would suggest: - Setup IDE breakpoints on requestInit(), requestComplete(), init() and on the method with the error message you noted (its there in a block of text) - Run the code with 1.5.4 and stepping through Stripersist go until it blows up... - Run the code with 1.5.3 and step through the same areas and see why that doesn't blow up... Doing this helped me learn a lot about Stripersist in the process and figure out how to solve our problem. BTW Stripersist is a well written encapsulated piece of code that helps bridge Stripes and (raw) JPA... I wouldn't expect updates... unless higher level functionality was built on top of it... and even then its compact size and simplicity makes it much better this way IMHO. The other option is trying to provide people with pieces of your code until someone can reproduce what you are seeing but that might be a much longer road to travel unless you can pack up a small reproducible test case.
