In order for this version of Eclipse to run, GTK2 libraries must be installed and available on the library path (i.e. LD_LIBRARY_PATH). To prevent errors with workspace locking, the following command line should be used to launch Eclipse: "eclipse -vmargs -Dosgi.locking=none" Otherwise, eclipse may fail to create a lock file with reason: "Workspace in use or cannot be created, choose a different one." There is a bug in the Oracle Java 7 64-bit JRE (b147) which may cause Eclipse to crash (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7070134). The crash can be avoided by using the -XX:-UseLoopPredicate VM argument (-vmargs -XX:-UseLoopPredicate). Alternatively, you can use a different JRE.
