Please install Java 6 for OS X and try again. Note that Java 8 does not work.

Apple's Java 6 for OS X is available at:

​https://support.apple.com/kb/DL1572?locale=en_US

Please confirm if this allows the build to succeed.

In the future, please use WikiFormatting and Cc the port maintainer(s) (port info --maintainers openni).

[ctreleaven (Craig Treleaven)]

I asked the reporter to verify that the port built successfully since we have limited buildbot coverage.

[jmroot (Joshua Root)]

Would be nice if something (the java portgroup?) could detect this situation and provide a more helpful error. Not sure how it would be done though.

[ogourgue (Olivier Gourgue)]

To be sure I understand well, you want me to reinstall Java 6 over my Java 8, right? It might have severe implications on other applications I'm using, no?

[ctreleaven (Craig Treleaven)]

I'm not a java expert; backups are always a good idea, etc. However, I understand that java is designed to accommodate multiple versions being installed and active at once. My system has Java 6 and Java 8 installed with no apparent ill effects.

Please let me know if you are unwilling to proceed and I'll close the ticket as "unverified".

[ogourgue (Olivier Gourgue)]

With the link provided above, Java 6 and Java 8 are indeed installed side by side. That solved my problem and openni is now installed correctly. Thanks for the support!

Thanks for reporting back.
