openjdk build failures on "nm"

Hi,

We get a lot of reports from pkg-fallout@FreeBSD.org for different openjdk versions. The errors seem to converge around "nm".

Some examples from different reports:
nm: 'ciMetadata.o': Invalid argument
nm: 'abstractCompiler.o': Invalid argument
nm: 'eventEmitter.o': Invalid argument

It also seems to happen on -quarterly and -default and on 13.5 and 14.2 and I see errors in openjdk 11, 17, 18, 20. But sometimes the build succeeds fine.

Is anybody looking into this? Or should we ignore it?

Regards,
Ronald.
