Another test handler has eaten my output – what now?

I have implemented test handlers, that parse test
output like this:

OK (8 tests, 8 ran, 7 checks, 0 ignored, 0
filtered out, 123 ms)

Unfortunately the build in
CnCppUnitTestHandlerFactory$CppUnitHandler eats up
all OK messages (using this regex: ".*((Run: )|(OK
\\()).*"). Since the output above is printed out
by a test framework, it's difficult to change.

Is there any way to prevent the CnCppUnit Test
Handler from parsing the output if my handlers
need them?

The current situation is, that my handlers parse
all test output, but the session can't be ended
since CnCppUnit “steals” the last session result
line which doesn't appear to my handlers though.
