[MJAVADOC-721] Parse stderr output and suppress informational lines

[jira-importer]

Markus Spann opened MJAVADOC-721 and commented

From Java 17 the Javadoc tool prints informational output to stderr mixed with actual errors and warnings (see JDK-8268774, JDK-8270831).

Currently the maven-javadoc-plugin logs the complete content of the tool's stderr as warning or includes it completely in the message of a MavenReportException (in case of an unsuccessful exit code of the tool). This behavior is not optimal with Java 17 onwards.

The output can be lengthy and the informational messages very distracting. This is particularly true for larger projects.

This improvement enables the developer/user to focus on the actual warnings or errors.
