Hi all fornax gurus,
I'm using in our project fornax with hibenrate, spring-framework and now we
have an issue during testing. If I try to run more than unit tests, I got
every time I OutOfMemoryError. My solution was to increase the Java heap
size like this -Xms256m -Xmx1024m, but this alternative hadn't solved the
problem (the same problem also came, when I try to run tests with maven
command mvn clean test). May be someone knows this issue and can give me
some tips and tricks or some advices, how I can fix that problem.
It seems like as if each test reloads the ApplicationContext and tries to
recreate an instance of the SessionFactory and I know that Hibernate
SessionFactory can be a memory hog.
Thanks for advance.
here is the stack trace:
