Compiling openjdk8 takes forever on RPI4.

[Ronald Klop]

Hi,

I'm using poudriere to compile ports. It runs on an RPI4 8GB.
FreeBSD jail13 14.0-CURRENT #6 main-34d696110: Sat Feb 27 05:01:05 CET 2021

Compilation is already going on for the second days. I have compiled this port in the past in a couple of hours. NB: this compiles fine in the official pkg builders.

I used jstack to look at what it is doing. The main stack which keeps showing up is this:

... more lines skipped for brevity...

The tail of the buildlog is:
...

And this is the last output for 32 hours already. I have no idea if the last logline has anything todo with the current activity of the compiling process.

Any thoughts on how to fix or debug this? Would it be a Java, OS or RPI4 problem?
