Mag Hoehme commented on SUREFIRE-628:
-------------------------------------

The reason for this behaviour seems to be as follows:

In class ConcurrentPrintStream.write(byte[], int, int), 
TestMethod.getThreadTestMethod() returns null when the endTest()-statement from 
the TestListener is printed. In this case, printing is delegated to the 
ByteArrayOutputStream out, which is never printed.

> Parallel Execution: Output from junit.framework.TestListener.endTest() is 
> swallowed

> I am using a junit.framework.TestListener to print some bookkeeping 
> information on System.out before and after the testcase.
> When executed single-threaded, everything works fine, and I am getting both 
> messages before and after the testcase. In parallel, only the message before 
> the start of testcase is printed, while the message after the testcase 
> disappears.

> Testcase output (single-threaded execution): both messages are printed
