This looks like the Apple article of interest:

According to the article, the page should be mapped with MAP_JIT.
Before instructions are written, pthread_jit_write_protect_np should
be called. After writing the jitted code, call
pthread_jit_write_protect_np again and call sys_icache_invalidate.

It looks like the OpenJDK folks are also experiencing similar issues.
