Re: [tycho-user] JUnit test fails on Mac 32-bit 
Note that on a 64-bit Mac you can still have a 32-bit JVM set as the default. You can pass -d32 on the command line to set the VM to launch in 32-bit mode. 

Conversely it is possible to have a 64 bit JVM on a 32-bit kernel. You can pass -d64 to the JVM to bring it up in 64-bit mode. 

Some of the auto detection in Eclipse is dodgy as it uses things like the OS to guess whether to load the 32 bit or 64 bit DLLs, which on Mac doesn't necessarily follow. 

Try -d32 to your vm opts to see if that helps.
