====== Error: Couldn't find per display information - JDK 1.6 on Linux ======
Running Spark on java 1.6.0 in Linux always gets the error:
Error: Couldn't find per display information

It is caused by a bug in jdic tray icon library. Latest version of jdic has solved this problem. https://jdic.dev.java.net/servlets/ProjectDocumentList?expandFolder=4183&folderID=5497

Notice that this problem did not happen in java 1.5. Some linux (as Fedora) have problems running spark with Java 1.5, after login, the windows is blank.
