guice-persist: "Work already begun on this thread." in production

[Alexander Urmuzov]

Hi!

I have an application that works perfectly in deveopment (kubuntu + tomcat 6.0.32 + MySQL) but fails with strange error in produnction (AmazonEC2 Linux + tomcat 6.0.32 + Amazon MySQL). The error is:

java.lang.IllegalStateException: Work already begun on this thread. Looks like you have called UnitOfWork.begin() twice without a balancing call to end() in between.

Servlets, that render html pages always work fine, but some JS/CSS resources that are included in HTML pages randomly fall with the error.

I use PersistFilter for all resources in my app:

        filter("/*").through(PersistFilter.class);

Guice version is 3.0-SNAPSHOT from https://repository.sonatype.org/content/groups/forge/

How can I fix this error? And why I can't reproduce it in development environment?
