Crash on MacOS X with version 2.0

[Former user]

Reported by philip: Hi,

when I install the plugin (version 2.0) on MacOS X (10.5) in JabRef 2.5 (and 2.6beta) JabRef crashes with the following error

Cannot launch Java application: Uncaught exception in main method: java.lang.UnsupportedClassVersionError: Bad version number in .class file

if I should provide any additional Information please tell me.

Cheers, Philip

Commented by philip: I started JabRef from the terminal to get some more debug information. That's what I got, I hope it helps:

Commented by jnothman: Like the conversation at http://bibsonomy.blogspot.com/2009/02/feature-of-week-bibsonomy-plugin-for.html, bibsonomy needs to ensure that they compile this plugin with Java 1.5, NOT 1.6 in order to be OSX-compatible.

Commented by iblis: No follow up on this ?

Any plan to make the plugin work on Mac OS X ? I mean just compile it with Java 1.5...

A workaround for this is to delete "BibsonomyProperties.txt" file under JabRef installation folder.

This will reset Bibsonomy configuration and allow you to correct its settings.
