Hi Tomasz,
I believe we added a workaround to the Ptolemy II svn repository.
In the svn tree, ptolemy/actor/gui/TextEditor.java is now:
/** Get the background color.
* @return The background color of the scroll pane.
* If _scrollPane is null, then null is returned.
* @see #setBackground(Color)
*/
public Color getBackground() {
// Under Java 1.7 on the Mac, the _scrollbar is sometimes null.
// See http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5574
if (_scrollPane != null) {
return _scrollPane.getBackground();
} else {
return null;
}
}

To my knowledge, Ptolemy II and Kepler compile and run properly

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:
