Cytoscape 2.6.3 startup eoor Centos + Java 1.6

[Stéphane Plaisance]

# starting up Cytoscape on Centos

If I answer OK to the startup error window, Cytoscape will close.
If I close the window, it will start but features will be missing in
the GUI (no text in the node pan table etc...)

I re-installed from scratch but it does it again. I presume this has
to do with my Java / VM version !

please help

It looks like you are loading a plugin that was compiled with a newer version of java (1.6.14 or greater). The plugin manager remembers plugins you previously loaded, so you might need to remove the track_plugins.xml file to reset the plugin manager. On windows, this is in "C:\Documents and Settings\<user>\.cytoscape\2.6\". You can turn on your console output, which may show you which plugin is failing. You can do this by adding the program argument "logger.console=true".
