Description

When we run multiple unit test with ANT command, each test class is run in its own JVM instance - we have to do that because many tests set up some static stuff - I don't want to discuss that in this ticket though - it works and must work this way for now.

However, when we run tests in IntelliJ, especially when we want to run all test classes from the whole package, or selected subset of tests, IntelliJ tries to run all of them in a single JVM which obviously leads to problems.

Frankly, IntelliJ introduced (I don't know exactly when) a new feature so that each test class can be run in a separate JVM, just like we do when we run with ANT. I this ticket I want to modify the default test configuration for IntelliJ so that it works in the way described above.
