JDK15 generally takes a very long time to compile. If you have more
than 1 cpu, you can add

MAKE_ENV+=HOTSPOT_BUILD_JOBS="n"

in the ports Makefile, where n is the number of cpus you have. This
will parallelize hotspot builds (the cpp parts) which is the most time
consuming part of building a JDK.
