Bug in resource import in LvgAnnotator?

Hi,

On line 579 in org.apache.ctakes.lvg.ae.LvgAnnotator there is the following resource import:
          ExternalResourceFactory.createExternalResourceDescription(
              LvgCmdApiResourceImpl.class,
              new File(LvgCmdApiResourceImpl.class.getResource(
                  "/org/apache/ctakes/lvg/data/config/lvg.properties").toURI()))
          );

The .getResource() call breaks when the package is imported as a jar (from Maven central), with an error stating that the "URI is not hierarchical". According to:
http://stackoverflow.com/questions/18055189/why-my-uri-is-not-hierarchical
the call should instead use .getResourceAsStream().

Is this a bug, or am I doing something wrong? I'm not very familiar with how Java handles resources in general.

Hi Jakob,
Yes, there is currently a limitation in the LVG component to have
their jar unpacked and added to the classpath.
I think there is an outstanding Jira to enable it read it from a jar
like the rest of the jars.  (There are some limitations such as
hsql/lucene not being able to read directly from a jar hence it's been
outstanding.)
