[platform-dev] VisualVM 1.3.3 / 1.3.4 often fails in looking up a Platform based app with OpenJDK 7u4, Mac OS X

[Fabrizio Giudici]

I'm running an application which is based on the Platform and embeds
OpenJDK 7u4 for Mac OS X. When I launch VisualVM (1.3.3 or 1.3.4), often
it doesn't see the process under "Local" (but sometimes it does). VisuamVM
runs with Apple JDK 1.6, but I think that it shouldn't matter. When
VisualVM doesn't see my app there's an exception in the status bar:

java.lang.NullPointerException

Any hint?
