I think I've seen this. Trying to remember what it was.

Do you have the wxallowed flag on the filesystem the jdk is running on?

What's the output of `mount`?

Thanks for hint,

I tried "wxallowed " and it worked well

openbsd-vm01# cat /etc/fstab
8bff342e8d813c9a.a / ffs rw,softdep,noatime,wxallowed 1 1
openbsd-vm01#

openbsd-vm01# java -version
openjdk version "1.8.0_265"
OpenJDK Runtime Environment (build 1.8.0_265-b01)
OpenJDK 64-Bit Server VM (build 25.265-b01, mixed mode)
openbsd-vm01#

Thought you might have a non-default partition layout. That's why /usr/local is a seperate mount point by default. It gets the wxallowed flag without enabling it for the whole system. The partition layout and their flags are part of the security settings.

Lecture aside, glad that fix it.
