Apache Netbeans 12.2 freezing.

Hi I'm using Netbeans to develop a PHP site and I'm having a problem with
recurring freezes of netbeans. Every time I'm working on a long page the
IDE freezes and I lose my job, being forced to kill the application. Sometimes
it takes several minutes to happen and sometimes it happens shortly after
opening the file. I would like assistance in solving this problem.
System information:

OS: Windows 10 Enterprise
Version: 1909
Compilation: 18363.1139
Processor: Intel(R) Core(TM) i3-6100T CPU @ 3.20GHz
Ram: 8,00GB
Java VM: 1.8.0_131-b11 32Bits
Version of Netbeans: Apache Netbeans 12.2 32Bits

I can not change the version of java ... company rules.
I appreciate the attention.

Guess it’s Ctrl-\ to send a break on a Mac. My terminal window cut off the dump, but what I have can be found below.

Also, this time around I was able to see some of the messages in the windows. They had messages like :


  *   Folder org-netbeans-api-project-libraries already exists in /Users/blah/Library/Application Support/NetBeans/ 12.2/config


  *   Cannot get exclusive access to /Users/blah/Library/Application Support/NetBeans/12.2/build.properties@bad1856d:5a70225a<mailto:Support/NetBeans/12.2/build.properties@bad1856d:5a70225a> (probably opened for reading)


Lastly, I tried to send the error report through NetBeans and a message came up in NetBeans saying there was no Network connectivity, but my network is fine.

Re: Apache Netbeans 12.2 freezing.

Posted by Mike Ryan <mr...@cornell.edu>.
I have updated my Java version to:

openjdk version "1.8.0_275"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_275-b01)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.275-b01, mixed mode)

This is Netbeans 12.2 on macOS BigSur 11.1

I haven’t run into the same weird issue with a hundred windows popping up complaining about file permission issues.

This time, after using Netbeans for about an hour, I suddenly was unable to save and the following was printed out in the terminal:

Exception: java.lang.ClassCircularityError thrown from the UncaughtExceptionHandler in thread "OpenIDE-request-processor-1"

Exception: java.lang.ClassCircularityError thrown from the UncaughtExceptionHandler in thread "Module-Actions"

Exception: java.lang.ClassCircularityError thrown from the UncaughtExceptionHandler in thread "Module-Actions"

Exception: java.lang.ClassCircularityError thrown from the UncaughtExceptionHandler in thread "Refresh-After-WindowActivated"

Exception: java.lang.ClassCircularityError thrown from the UncaughtExceptionHandler in thread "Module-Actions"

I’ll try to get a thread dump next time. (Wasn’t sure what the macOS version of Ctrl-Break was – found out that it’s not Ctrl-C!) 😊

Thanks, Lars. I, too, am using an outdated version of Java 8. I’ll update that and get back to using 12.2!

I suspect you are affected by [NETBEANS-58]
(https://issues.apache.org/jira/browse/NETBEANS-58).

You can verify if this is indeed the case by following these steps:

1. Start the NetBeans IDE from the command line (not from the Start
Menu). This will give you an associated console window.
2. Use the IDE as you normally would and wait for the freeze to happen.
3. Press Ctrl-Break in the console window. There will now be a thread
dump in the console window. Copy all of that text into a text file. If
you can find the text
"sun.net.www.protocol.http.NegotiateAuthentication" then you are
indeed affected by this bug. If you cannot find that text, then your
problem is something else and you can stop reading this response. (you
can post the thread dump on this mailing list if you like)


This bug was eventually solved in the JDK itself, not in NetBeans
code, so to make it work you need to be using at least Java 8u251 for
running the IDE.   And you seem to be using something quite a bit
older.

If you insist on using that old Java then you may be able to
circumvent the issue by using another type of proxy ... if your
company policy allows.

PS: Wow!  It is rare these days to see 32-bit Java in use. I don't
think 32-bit vs 64-bit is relevant to the case at hand I'm just
surprised that 32-bit Java is still out there. :-)
