Quickly, where do we look? I can't seem to find where the "javac" command is called in the C interface.
Where is the java code that runs the parser/compiler? Ok, thanks gotta run ably.

Couldn't you just look?
src/java.base/unix/native/libjli/java_md_solinux.c:79

It's part of the Java launcher, jexec.c. The easiest way to discover
this stuff is to run javac in a real C++ debugger.
