What is the current working directory for solrconfig.xml RunExecutableListener

[Jacob Singh]

I tried:

<listener event="postCommit" class="solr.RunExecutableListener">
      <str name="exe">snapshooter</str>
      <str name="dir">bin</str>
      <bool name="wait">true</bool>
      <arr name="args"> <str>arg1</str> <str>arg2</str> </arr>
      <arr name="env"> <str>MYVAR=val1</str> </arr>
    </listener>

However, it doesn't seem to work.  I assumed that it default to the
solrhome, but that doesn't seem to be the case...

Is it defaulting to the jetty root?  Or the conf dir?

Thanks,
Jacob
