I’m trying to build JDK 9 on Ubuntu using Docker. My build hangs at this point:

Warning: generation and use of skeletons and static stubs for JRMP

encouraged to migrate away from using rmic to generate skeletons and static

How can I can more info to debug the problem?
make LOG_LEVEL=debug
Also see what processes are running at that point. You are on a "low
power" system (1 core, 2G) so you may just be hitting an intensive part
of the build - like building docs maybe?

JDK 9 used to build successfully in this environment (maybe 2 months ago). I’m
not sure when this started.
