Reduce noisy output when running some CPE tests when run in Maven
-----------------------------------------------------------------
Key: UIMA-585
URL: https://issues.apache.org/jira/browse/UIMA-585
Project: UIMA
Issue Type: Test
Components: Collection Processing
Reporter: Marshall Schor
Assignee: Marshall Schor
Priority: Trivial
Fix For: 2.3
Many CPE tests use ManageOutputDevice.setAllSystemOutputToNirvana() calls to
attempt to stop expected error output from flooding the console. This works
when the tests are run from Eclipse, but fails when run from Maven. This
because the mechanism used is to swap in to System.err and System.out new print
streams that throw away their output. However, if any logging occurs previous
to this, the logger will initialize and copy the System.err, for example, so
that subsequent setting of it has no effect on logging. When running from
Maven, this happens.
The fix is to use a different mechanism to stop the output due to logging:
UIMAFramework.getLogger().setLevel(Level.OFF). Ideally this is surrounded by a
try / finally block to insure it's put back to INFO.
