Hi Pavel,
As awt team has committed the related
bug(http://hg.openjdk.java.net/jdk8/awt/jdk/rev/96340349e35b), I
prepared the webrev for this bug(7129742

Hi Sean,
Hi Pavel,
Thanks for your comments.
About the 1st question, I modified the testcase a little to
demonstrate the problem, testcase is pasted at the end.
If textArea.setEditable(true) is executed, the frame disposes,
but application doesn't exit.
If textArea.setEditable(false), the application exits as normal.
java 1.7.0_01 and latest java8 code are tested. And TextField
contains this problem as well. I'll add it to fix later.
Shall I report a separate bug for it ?
Yes. I think it will be better if you fix the described above
problem as a separate bug. Note that it should be reviewed by the
AWT team...
About the 2nd question, I was driven by the comment "// TODO :
fix this duplicate code". Is there any strong reason to keep it ?
I'm absolutely agree with removing duplicate code. My second
question was about added by you
"jtext.getCaret().setVisible(false)" in the XTextAreaPeer.java
class. I wrote:
2. Why don't we need the same code in the XTextFieldPeer class?
As I can see you've noticed that XTextFieldPeer should be fixed as
well (in a separate fix with XTextAreaPeer)
Regards, Pavel

Hi Sean,
I have a couple questions about the following code in the
XTextAreaPeer.java class
+ // visible caret has a timer thread, which must be
stopped
+ jtext.getCaret().setVisible(false);
1. Why this code wasn't needed before your fix, when caret
was visible for enabled text area?
2. Why don't we need the same code in the XTextFieldPeer class?
About the bug7129742 test:
Because of the passed field is used from different threads
you must use synchronization or mark the field as a volatile.
Regards, Pavel
Hi Alexander,
XTextFieldPeer and XTextAreaPeer have a same inner
class XAWTCaret, and in XTextAreaPeer there is also a
comment:
"// TODO : fix this duplicate code " before XAWTCaret . So
I removed the XAWTCaret in XTextFieldPeer and changed the
XAWTCaret into a static class, so XTextFieldPeer can
use XAWTCaret from XTextAreaPeer .
As XAWTCaret is only used in the following
method in both XTextAreaPeer and XTextFieldPeer .
protected Caret createCaret() {
return new XAWTCaret();
}
I think this modification should not bring side effect.

Thanks
