Marshall Schor commented on UIMA-5324:
--------------------------------------
for (1): have the UIMA logger facade go (by default) to the SLF4j facade. This
allows UIMA to not have its own back-end for logging, and to pick up and use
whatever back-end logging might be configured in an embedding application.
for (2): include the slf4j-jdk14 jar in the UIMA binary distribution. The
out-of-the-box launchers configure the class path to include this jar. This
jar is the slf4j back-end connection to the built-in-to-Java logger, which was
the v2 default, so by out-of-the-box default, logging will be like it is in v2.
for (3): add a new JVM system property: -Duima.suppress_annotator_logging. If
specified, then annotator loggers are suppressed. The implementation will only
suppress logging by loggers obtained using the standard methods on the
Annotator base implementations, one of uimaContext().getLogger(), or
getUimaLogger(), or getSlf4jLogger().

>
> per discussion on dev list:
> 1) Make UIMA more embeddable by having it able to not have its own back-end
> for logging.
> 2) Never-the-less, have the out-of-the-box experience do reasonable logging.
> 3) Provide a simple, not logging-back-end-specific, way to globally suppress
> logging from Annotator code.
