I am running OS X 10.10.5; Have downloaded Open Studio w/ DQ. Running TOS_DQ-macosx-cocoa thros the following error:
error loading hook: org.talend.osgi.configurator.JarLoaderConfigurator
I had Java 8 installed and Open Studio asked me to install Java 6. I installed java 6 and got the above error.
Terminal shows this Java version:

Hi,

I had Java 8 installed and Open Studio asked me to install Java 6. I installed java 6 and got the above error.

Could you please indicate the DQ build version you are using? Talend 5.X?
Actually, this problem "Unsupported major.minor version 52.0." is usually caused by "a higher JDK during compile time and lower JDK during runtime".
Did you compile your job using java 8 and run it using Java 6?
Have you tried to go to Window > Preferences > Installed JREs, selecting Edit and browsing for the appropriate JDK to see if it works?
Best regards
Sabrina

I am not using Windows, as previously mentioned.
I got it to work.

Dear Christopherhorn01845,
I am on similar hardware and am experiencing the same issue:

java.lang.UnsupportedClassVersionError: org/talend/osgi/configurator/JarLoaderConfigurator : Unsupported major.minor version 52.0

Any chance of you sharing how you solved the problem?
Cheers JP
