Waiting sounds good.<br>
It would be good if a few Kepler developers would switch over to
Java 1.7, especially Windows.<br>
<br>
Under Mac OS X, I downloaded Java 1.7 and updated ~/.bash_profile:<br>
export
JAVA_HOME=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home<br>
export PATH=${JAVA_HOME}/bin:${PATH}<br>
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
export ANT_OPTS=-Xmx2048m<br>
<br>
However, 'ant run' fails for me in the devel tree, even with 4g of
space. I get<br>
[compile] The system is out of resources.<br>
[compile] Consult the following stack trace for details.<br>
[compile] java.lang.OutOfMemoryError: Java heap space<br>
<br>
I don't have time to track this down today.<br>
<br>
Under Mac OS X, Java 1.7 produces the following stacktrace when I
start up Ptolemy II:<br>

Hi Christopher,
<br>
<br>
Thanks for the fix. I agree with you that it'd be good to fix the
ptII
<br>
branch in svn for Kepler 2.3. Before creating a new patch release,
I
<br>
would wait until we've had more time to test since there could be
<br>
additional Java 7 problems.

It looks like the problem has to do with Java 1.7. I was able to
<br>
reproduce this on the Mac
<br>
with two different early release versions of 1.7. The bug occurs
in
<br>
Ptolemy II, outside of
<br>
Kepler.
<br>
<br>
The bug report is at
<br>
<br>
<a class="moz-txt-link-freetext" href="http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5574">http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5574</a>

The fix is to modify ptolemy/actor/gui/TextEditor.java to check
if
<br>
_scrollbar is null:
<br>
<br>
public Color getBackground() {
<br>
// Under Java 1.7 on the Mac, the _scrollbar is sometimes null.
<br>
// See <a class="moz-txt-link-freetext" href="http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5574">http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5574</a>
<br>
if (_scrollPane != null) {
<br>
return _scrollPane.getBackground();
<br>
} else {
<br>
return null;
<br>
}
<br>
}
<br>
<br>
I'm not sure why this is happening, but I suspect the problem is
that in
<br>
Java 1.7
<br>
setBackground is calling getBackground on subcomponents and the
TextEditor
<br>
subcomponent is not completely instantiated.
<br>
<br>
There could be other places where this problem occurs. I'll
switch over
<br>
to Java 1.7 and see
<br>
what turned up. It would be worth running the debugger and
verifying
<br>
that we are in the
<br>
Swing Event Thread when the problem occurs.
<br>
<br>
I'll leave it to the Kepler Team to decide how to handle this.
My
<br>
proposal is that I patch the
<br>
ptII branch used in the release with the above change. I'd like
to wait
<br>
until a few people have exercised
<br>
Kepler under 1.7 before doing so though. If we patch the ptII
tree used
<br>
in Kepler-2.3, then at
<br>
least people who are working from the 2.3 tree can get the
update. I'm
<br>
not sure about releasing
<br>
a patch release to Kepler, that is up to others.

Hi Edward and Daren,
<br>
<br>
"Listen to Actor" is invoked from the context menu on the
canvas,
<br>
and the exception is also thrown when double-clicking on the
Python
<br>
Actor to edit the script. These are probably run from the
Swing
<br>
event thread.
<br>
<br>
Daren, thanks for verifying this problem occurs with Java 7
but not 6.
<br>
I updated Kepler a few months ago so that it would compile
with Java 7.
<br>
However, when I ran it, I didn't exhaustively test all the
<br>
functionality. I'll create bug report so this error is not
forgotten.

This sort of thing can happen for GUI code that invoked
outside

the Swing event thread. How is this being invoked? If it's
just

from the menu, then I presume it is in the Swing event
thread...

Hi Daren,

I get the same behavior with Windows 7. The error is the
same for

both "Listen to Actor" and editing a Python script:

I installed Kepler 2.3 on Windows with the installer
