There is one problem with Java 1.7 I know of. When you try to edit the script
in PythonScript actor, you get an exception: "Failed to open a dialog to edit
the target" with the stacktrace starting with:

    java.lang.NullPointerException
        at ptolemy.actor.gui.TextEditor.getBackground(TextEditor.java:144)

AFAIR, there was some discussion about this problem, but I do not think we got
to solve it anyhow. Also, it probably concerns not only the PythonScript actor.


Some information about my environment: (this is the latest java 1.7)

    $ java -version
    java version "1.7.0_09"
    OpenJDK Runtime Environment (IcedTea7 2.3.3) (ArchLinux build 7.u9_2.3.3-1-x86_64)
    OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

I am using kepler-2.3 from:
http://code.kepler-project.org/code/kepler/releases/release-branches/kepler-2.3


Here is the whole stacktrace:
