How to diagnose lock up with 12.5 Beta 1
Hi folks,
I've been using 12.5 Beta 1 for a couple of days, and I'm experiencing
occasional lock ups. There doesn't seem to be any particular interaction
on my part that is triggering it, and the memory usage appears to be
stable with plenty of free space.
Is it possible to attach to the running process and get a stacktrace?
I'm not seeing anything log file entries that could help me understand
the problem.
My system is:
Product Version: Apache NetBeans IDE 12.5-beta1
Java: 11.0.12; OpenJDK 64-Bit Server VM 11.0.12+7-post-Debian-2
Runtime: OpenJDK Runtime Environment 11.0.12+7-post-Debian-2
System: Linux version 5.10.0-8-amd64 running on amd64; UTF-8; en_GB (nb)
Regards,
Chris

It's at https://cwiki.apache.org/confluence/display/NETBEANS/Bug+Priority+Guidelines
It's meant to be how we triage issues during the release process. The
extent to which that information should be user-facing is open to
question. A simplified version might be better?
Or we remove bug priorities from users completely and figure out a
better way for developers to triage?
Certainly my experience from release managing is that the current way
of handling JIRA issues and their priorities is not fit for purpose.

Yes, that was me on NETBEANS-5913 after confirmation from a stack
trace in a related issue. NETBEANS-5914 should be same status?
Best wishes,
Neil

Amusingly I was going to set this issue's priority to blocker since I
recalled that was appropriate for an identified deadlock in the before
time, but it happened as I was getting ready to do it.

Can you try with a different JDK to see if that makes a difference — just
to exclude that possibility?

Hi all,
Another freeze, this time with the Azul JDK 11. In the trhead dump I can
see that it again is waiting on locks in both the AWT Event Queue and
the Editor Parsing Loop.
I've added a new thread dump and copy of the messages.log file to the
Jira issue.
Regards,
Chris

Just curious what kind of features are active? Is it default Java, Java Web and EE, Groovy?
Any particular plugins active (i.e. nb-javac, Spring-Boot, etc.)?

Thanks. If/when it happens again, see what you get in the thread dump
and see if it's stuck in either of the two places mentioned in my
previous email. Be good to know if either (or both) are common to all
occurrences.

Hi Neil,
On this occasion I had just selected New -> Java Class in the Projects
window. However, on other occasions lockups have occurred when I've just
hit Ctrl-S to save some changes to a file or I've just left the IDE idle
for a while.

I may be wrong, but it looks like all yours are a deadlock at
https://github.com/apache/netbeans/blob/master/ide/projectapi/src/org/netbeans/spi/project/support/DelegatingLookupImpl.java#L168
?
At a guess the call to setLookups in the synchronized block is a
problem as that fires a bunch of notifications?

I experienced some other deadlocks in NetBeans 12.4 before, but only on startup. After examining the thread dumps I can't immediately see if they are the same bug or not (they could very well be a separate bug). In any case, I uploaded those thread dumps here:

Very interesting perspective. Never thought of it like that -- though it would help if it could be narrowed down some other way though.

Ah, OK. I can see that it would be ideal to see thread dumps with the crash from a "vanilla" OpenJDK or Zulu distribution.
Whenever I see an intermittent bug like this, though, my instinct is to avoid changing my configuration, in case the bug stops being reproducible. Then I will never know what caused it, or when it will return...

True, and pointed out one possible sign of that happening already.
However, I'm still of the view that trying to reproduce with a non-distro JDK build is useful. I've had distro builds that behave differently, crash in odd places, and even manage to run more than one EDT at the same time.

However, I'm still of the view that trying to reproduce with a
non-distro JDK build is useful. I've had distro builds that behave
differently, crash in odd places, and even manage to run more than one

Sure, true. But surely it would be relevant to know whether JDK choice
makes a difference?

RE: How to diagnose lock up with 12.5 Beta 1
Posted by Eirik Bakke <eb...@ultorg.com>.
But if the problem goes away with a different JDK, that doesn't mean the bug is in the JDK--it just means the bug cannot be reproduced.
For example, if two different NetBeans threads acquire nested locks in opposite order, that would be a deadlock bug--but the actual deadlock would only occur if those two critical sections happen to run at exactly the same time. But it would be a bug which should be fixed in NetBeans in any case.

Why is it useful to try a different JDK here? See my earlier comment.

Could you, please, see if the problem continues to occur when you use a few different JDKs?

Could you, please, see if the problem continues to occur when you use a few
different JDKs?

Hi Geertjan,
None of my projects use Micronaut, they are all Spring Boot based. If I
do a:
mvn -DincludeScope=runtime dependency:tree
Then no Micronaut dependencies are showing up.

I think that will run whenever the module is enabled, so whenever the
enterprise cluster is active? Looking at the dump, the EDT appears to
be waiting on the Editor Parsing Loop, and that is stuck waiting on
something in the document? So are the EDT and parsing loop
deadlocked? And if so, which is calling something it shouldn't?

OK, I've just had another lock up. I wasn't able to get a thread dump
with jstack, even using the -F flag, but succeeded with VisualVM. I've
created a Jira issue and attached both the thread dump and log file to it:

As Geertjan said, not 17, but also I would try a different vendor -
eg. Azul or AdoptOpenJDK. I've found distro packaged JDK's a little
flaky at times, at least with Ubuntu. You don't have to install, just
unpack and point the IDE to it with the jdkhome setting.
VisualVM could be a good, easy way to diagnose what's going on.
Best wishes,
Neil

Probably not 17, since it hasn't been released yet.

Hi Geertjan,
I'll install OpenJDK 17 from Debian's repositories and try that. I get a
lock up roughly twice a day, so I'll see if a more recent JDK makes a
difference.

Chris

I'd try different versions of the JDK first, to see if doing that makes a
difference.

Do these lockups occur only during startup (e.g. when loading projects and the like), or long after the IDE was first started?

When a deadlock occurs, it's probably more likely to come from a bug in NetBeans rather than a bug in the JDK. If changing the JDK appears to make the bug go away, I'd suspect it's just due to race conditions being affected by random timing changes (e.g. due to different garbage collection settings). So for debugging purposes it's better to keep using the JDK that reproduced the bug.
I find the thread dump from VisualVM to be useful for debugging deadlocks.

Lock up can usually be diagnosed with a java thread dump. Create the
dump (search for how to, it's based on OS), attach it to a bug report,
post a message in this list that the dump is available. Sometimes
multiple dumps can be useful, add them to the bug report as you get
them. NetBeans log attached to the bug report can also be useful.
