---------------------------------------------------------------
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.-- add a new API method:
suppressAnnotatorLogging(boolean). This API will be both global (in the
UIMAFramework class as a static), and in the UimaContext; the global one
overrides. 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().

> Key: UIMA-5324
> URL: https://issues.apache.org/jira/browse/UIMA-5324
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework
> Reporter: Marshall Schor
> Assignee: Marshall Schor
> Priority: Minor
> Fix For: 3.0.0SDK-alpha02
>
>
> 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.
