OSGI classloading error when viewing preference page in Eclipse Luna on Mac OS X Mavericks

[jacobythwaites]

The following log entries show what happens when I try to view the Compiler preference pane in Eclipse. I have Erlide version 0.24.0.201310150801.

Thanks for the report. I have not tested yet with any Luna releases, it might be that some things have changed (we are using some internal APIs). I will check it out.

[vladdu]

I have fixed the code, but the changes are incompatible with earlier Eclipse releases. We need a separate track and separate binaries. I will make an announcement when it's done.

This has been released a while ago, forgot to announce it.
