Minor Description
When fixing DFDL-2694, we found that the cli.expect function isn't able to read the trace output. Instead the test_CLI_Tdml_Trace_singleTest fails with the following:
net.sf.expectit.ExpectIOException: Expect operation fails (timeout: -1 ms) for matcher: contains('parser:')
We can the trace output on the console, so it is unclear why expectit cant. Some preliminary research shows the cli tests output to a PipedOutputStream, and may be a good place to start.
