Re: Java EE8 Status
Hi Som, Great to meet you, and thanks for the post. I believe that if you were to invest time into learning how to develop Java EE 8 and “Jakarta EE” applications with NetBeans, then you would be on a path to success. Java EE 8 is still modern, although it will be outdated within the coming years. However, if you look toward development with the Jakarta EE Platform (newer Java EE platform that was open sourced under Eclipse Foundation), then I think you will find that it fits into your “b” category: Established and stable. Jakarta EE 8 uses the same API as Java EE 8, so you should be able to translate any tutorials of Java EE over to Jakarta EE without much trouble. Jakarta EE 9 introduces a new namespace, which will change things a bit, although the APIs will remain much the same as the standard Java EE/Jakarta EE 8 APIs. Hope this helps.

Re: Apache Netbeans 12.2 freezing.
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!) 😊 -Mike From: Mike Ryan Date: Friday, January 8, 2021 at 8:05 AM To: Cc: users@netbeans.apache.org Subject: Re: Apache Netbeans 12.2 freezing. Thanks, Lars. I, too, am using an outdated version of Java 8. I’ll update that and get back to using 12.2! -m From: Lars Bruun-Hansen Date: Friday, January 8, 2021 at 2:21 AM To: Ronaldo Cc: users@netbeans.apache.org Subject: Re: Apache Netbeans 12.2 freezing. 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. Lars 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. :-) On Thu, Jan 7, 2021 at 8:13 PM Ronaldo wrote: > > Hi I'm using Netbeans to develop a PHP site and I'm having a problem with > recurring freezes of netbeans.
