Anton,
I finally caught this error in production. I patched our code to launch a JVM
(with mergesort) using your test case, modifed to output the JVM version
followed by the output when this error occurs. The output is as follows:

Comparison method violates contract
Anton,
Thanks for looking at this. Sorry I don't have a test case to give you yet. For
sure the machines are using JDK7u80 that are reproducing the error. The common
case is that the user is copying text from an email client and then pasting it
in to a JTextField. So I imagine that the content type of email is a factor in
producing this issue.
What I'll do is convert your ClipboardDump into the codebase so that I can just
log that information as soon as it happens. We'll see how long it takes to
catch this fish.
Thanks,
Jason

Hi Jason,
I've commented in the bug report:
Couldn't reproduce locally.
Please next time the problem is reproduced on your side, run the small
program below and attach its output to this bug (or file a new one).
Make sure NOT using the system clipboard from the moment of exception
till running the test program.
import java.awt.*;
import java.awt.datatransfer.DataFlavor;
public class ClipboardDump {
public static void main(String[] args) {
System.setProperty("java.util.Arrays.useLegacyMergeSort", "true");
DataFlavor[] dataFlavors =
Toolkit.getDefaultToolkit().getSystemClipboard().
getAvailableDataFlavors();
for (DataFlavor df: dataFlavors) {
System.out.println(df);
}
}
}
Please also make sure you are running 7u80 (not an earlier version)
since the Comparator fix was integrated to 7u80
Thanks!
Anton.

Hello Swing-Dev,
Recently we have updated to JDK7u80 and have noticed a pattern of users

=============
When I check the issue tracker http://bugs.java.com/view_bug.do?bug_id=8023043
shows as fixed in 7u60. Did this get fixed in 7u60 through 7u80? The stacktrace
is a little different from that bug so should I file this as a new issue?
Thanks,
Jason
