Subject RE: Possible Bug in Java 8 u 112 in javax.swing.JEditorPane.setText leads to stuck UI
Date Wed, 01 Mar 2017 06:02:48 GMT
Hi Philippe,

 

If you set the content type before setting text, it is not taking much time. It is just 2-5
seconds.

You can set the content type using javax.swing.JEditorPane.setContentType(String) API.

Eg: editor.setContentType("text/plain"); // or editor.setContentType("text/html");

 

I updated the test case which you shared along with bug and attached.

 

I hope it will resolve your issue.

 

Regards,

Muneer

Hello Guys,

Any chance that a P4 bug is fixed ?

It unfortunately affects us badly whenever some text (more than 700K which is frequent for
HTML pages) is received in our tool.

 

For my information what does this mean:
ILW = MLH = P4 

Thanks

Hi Philippe,

It's marked P4 because it is seen as a corner case issue.

Hi,

Previous sample showed already very slow rendering when text contains
spaces.

Now for the text without space. Sample attached.

Regards

Hi Philippe,

Your incident has moved to JDK-8172336: https://bugs.openjdk.java.net/
browse/JDK-8172336

I tried to reproduce the issue, but I could not reproduce this issue with
the information shared in the bug report. If you can provide a standalone
test case, it will be great. Also, please let us know if you observe the
same issue with JDK 8u122-ea and JDK 9-ea.
Have you observed the same issue with other OS(Other than Mac OSX) ?

8u122-ea is available here : https://jdk8.java.net/download.html
JDK 9-ea is available here : https://jdk9.java.net/download/

Regards,
Muneer

Greetings,
First best wishes for 2017.

I'd like to report what seems to be a critical bug we face in JMeter
. I noticed it under Mac OSX El Capitan.

Calling javax.swing.JEditorPane.setText() from AWT Thread with some
long text (without spaces) leads to what seems to be either a very
long or infinite loop, I made thread dumps and I have always  such
(partial)
