>Description:
I'm using a Java application running under Linux emulation.
It sometimes hangs and ps says it's in futex:
ps -alxwww | grep java
1000 20124 19935 581925 83 0 37599660 110892 futex Sl+ ttyp7 0:02.57 /usr/pkg/java/oracle-8/bin/java -cp /usr/pkg/PDF-Over/lib/* at.asit.pdfover.gui.Main file.pdf
Usually I can CTRL-C and restart it, and about 1/3 or 1/5 of tries
I can finish what I want to do with it.
>How-To-Repeat:
Install PDF-Over by downloading
https://webstart.buergerkarte.at/PDF-Over/setup_pdf-over_linux.jar
Install it using oracle-jre8-8.0.202:
oracle8-java -jar setup_pdf-over_linux.jar
Run it, using some variant of
/usr/pkg/bin/oracle8-java -cp "/installation/path/PDF-Over/lib/*" at.asit.pdfover.gui.Main "$@"
on a PDF file.
Sometimes it hangs before displaying the first screen, i.e. it pops up
a new window but that window stays gray. If you get further than that, just
ctrl-c and try again.
>Fix:
Yes, please!

I'm told that this can also be reproduced in the following way:
Using the Metalworks demo
(/usr/pkg/java/openjdk8/demo/jfc/Metalworks/Metalworks.jar from the
opendjk8 package):
Start it, select the "About" dialog from the help menu and click the OK button.
I forgot to mention that this wasn't working better on the
thorpej-futex2 branch last I tried.

I compiled
https://github.com/linux-test-project/ltp/releases/download/20230127/ltp-full-20230127.tar.bz2
on a CentOS (exact version unknown, sorry) and copied the contents of
testcases/kernel/syscalls/futex (see
https://github.com/linux-test-project/ltp/tree/master/testcases/kernel/syscalls/futex)
to a NetBSD 10.99.2/amd64 system and ran them. The output shows quite
a number of problems (look for 'failed' and 'broken' below):

tst_test.c:1152: TCONF: Test needs to be run as root

Perhaps these are easier-to-debug cases?
