Which of the Platform Modules makes app process unique?

Question

In Netbeans Platform application I wanted to turn off all unneeded modules, so I went to Project Properties > Libraries and turned off the platform module group. After that some warnings appeared about dependencies and I've clicked Resolve in the same window.

After that app builds just fine, but when I run it, I get the next error:

/Applications/NetBeans/NetBeans 7.1.app/Contents/Resources/NetBeans/harness/suite.xml:498: The following error occurred while executing this line:
/Applications/NetBeans/NetBeans 7.1.app/Contents/Resources/NetBeans/harness/run.xml:193: The application is already running within the test user directory.
You must shut it down before trying to run it again.

I'm 100% sure that no other instance is running, so it probably conflicts with IDE itself.

Do you have any idea what module should be turned on to solve this problem?

Answer 1

OK, I've found at last what modules are messing up all the stuff.

It's NetBeans OSGi Integration or NetBeans Equinox Integration module in platform cluster. They both are dependent on each other as well as on OSGi Specification module. When they are added back the app runs as intended.
