title: show console in runtime eclipse plugin
body: <p>I'm developing an eclipse plugin. It uses a type of grammar to process texts. The grammar can be composed and compiled. I have an existing tool that compiles the grammar. This tool displays errors in console if the grammar has any.</p>
  
  <p>When I run my eclipse plugin, a new eclipse instance opens. If I load a grammar and compile it in my new eclipse instance, the error are still printed to the old eclipse. Is there any way to redirect the message from old eclipse to the new eclipse instance?</p>
