All reports of jar-not-in-usr-share for the archive. The extended description of this tag is:
The classpath listed in some of the files references files outside of /usr/share, while all installed JAR files must be within /usr/share/java for libraries or /usr/share/package for JARs for private use.
The rationale is that jar files are in almost all cases architecture independent and therefore should be in /usr/share. If the jar file is truly architecture dependent or it cannot be moved since symlinked jar files are not accepted by the application, then please override this tag.
Refer to Debian policy for Java section 2.2 (Building Java packages) and Debian policy for Java section 2.3 (Java programs) for details.
This tag has not been emitted in any package tested by Lintian.
