Fixed optional dependencies that were marked as required in module-in… (

#1669)

* Fixed optional dependencies that were marked as required in module-info.java

* * Upgraded bundle plugin to fix https://issues.apache.org/jira/browse/FELIX-6259.
* Windows requires the use of ${file.separator} to separate classpath entries.

* Need to use a different log4j-slf4j-impl artifact under Java 11.
