Re: [ljc] Cross-JDK compatibility issue

From: Martijn V.

Hi James,

The situation is a little complex :-)

* Apple still maintains Java 6 on 32 and 64-bit Mac OS X

* Oracle maintains Java 7 64-bit Mac but has dropped support for 32-bit Mac (if it happens to work, great)

* Henri Gomez and others that contribute to the OpenJDK are still trying to provide 32-bit Mac compatibility, but it's on a best efforts basis

So you probably should do two things:

1.) Report the bug to http://openjdk.java.net/projects/macosx-port/ project so that Henri etc have a chance to fix it (please submit as much detail as possible)

and/or

2.) Detect OpenJDK 7 on 32-bit Mac and state it's not supported + add that to the FAQ as well

Cheers,
Martijn

So I've forked an open source project and put it on Github. Travis-CI is employed, but I've hit a snag:

- OracleJDK7 and OpenJDK6 pass green
- OpenJDK7 fails a test, consistently the same one

I'm on OS X[masked] with Oracle's latest and greatest, and an OpenJDK from the google-code site. I cannot reproduce the problem locally.

The only thing I've found in searching for clues is that OpenJDK is apparently a bit dodgy in 32-bit forms. Travis appears to be 32-bit.

As an engineer I'm looking for a solution. As someone with a few month's experience with Java / Maven / etc, I am rather lost at this point.

Explaining that "it works except on 32-bit OpenJDK7" in the readme would suck... Can anyone offer advice/assistance to help avoid that?

Thanks,

James
