Native Package Problem

Question

I'm trying to produce a native .dmg using Air 2.0.2, however I encounter the following issue:
adt -package -target native app.dmg app.air
unexpected failure: Copy failed
java.io.IOException: Copy failed
at com.adobe.air.nai.DMGPackager.assembleInternalFiles(DMGPackager.java:52)
at com.adobe.air.nai.NativePackager.createPackage(NativePackager.java:76)
at com.adobe.air.ADTEntrypoint.parseArgsAndGo(ADTEntrypoint.java:132)
at com.adobe.air.ADT.parseArgsAndGo(ADT.java:182)
at com.adobe.air.ADTEntrypoint.run(ADTEntrypoint.java:68)
at com.adobe.air.ADT.main(ADT.java:128)
I get the same when I try to use adt from the .swf/.xml
Any help appreciated.

Solved,
running eclipse with a different JRE (C:\Program Files\Java\jdk1.7.0_06\bin\javaw.exe) has solved the problem.
To do that I simply edited my eclipse.ini and added -vm C:\Program Files\Java\jdk1.7.0_06\bin\javaw.exe, here my
eclipse.ini:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
