Rick Hillegas commented on DERBY-6999:
--------------------------------------
Thanks. I will work with the following command line from run.bat and see if I
can get this to run outside JUnit. Debugging under either JUnit or maven would
be difficult:
{noformat}
java -cp target/lib/*;target/classes;target/test-classes
org.junit.runner.JUnitCore sk.palo.liska.ServiceImplTest
{noformat}
I'll let you know if I have trouble. Thanks.

> Setup: transaction management with spring + hibernate.
> Test code is here: [https://github.com/paloliska/tooMuchContention]
> - _master_ branch has derby version 10.13.1.1, hibernate 4.3.11, and spring
> 4.3.7.
> - _latest_dependencies_ branch has latest versions.
> Run test with:
> {code:java}
> mvn test
> {code}
> Tests are not stable. But with proper setup, you could make to fail all of
> them. Depends on current hardware, load. In Tests also could be set number of
> threads and timeout for each test. Test will run until timeout or fail.
