Description

When a project has limitToProject enabled and a type system descriptor imports another descriptor from a JAR file that is a dependency of the project, then an NPE is triggered:

Caused by: java.lang.NullPointerException
	at org.apache.uima.tools.jcasgen.Jg.isOutOfScope(Jg.java:723)
	at org.apache.uima.tools.jcasgen.Jg.generateAllTypesFromTemplates(Jg.java:630)
	at org.apache.uima.tools.jcasgen.Jg.main1(Jg.java:565)
	at org.apache.uima.tools.jcasgen.Jg.main0(Jg.java:418)
	at org.apache.uima.tools.jcasgen.maven.JCasGenMojo.execute(JCasGenMojo.java:198)
	at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:133)
	... 20 more

The reason is that the imported type system has a URI like "jar:file:.../third-party.jar!/desc/type/ImportedTypeSystem.xml" which translates to a path value of "null" because it does not reside on the file system.

In such a case, the TSD should simply be considered to be out-of-project.
