Yes. This is in context of Graal VM's native images. AFAIK there is no full xawt support yet. This is about the conflict of libawt and libjavajpeg. There are probably more.

Yes. This is on Linux x86_64 and with an OpenJDK built with GCC 10+. With gcc 10+ `-fno-common` is default:
So the `libjavajpeg.a`, and `libawt.a` got compiled with `-fno-common`. Then when being linked into an executable together, the linker screams with this:
collect2: error: ld returned 1 exit status
