Unsure exactly who should review this ... bug: https://bugs.openjdk.java.net/browse/JDK-8199768 webrev: http://cr.openjdk.java.net/~dholmes/8199768/webrev/
CompilerUtils.compile compiles all source files in a given directory tree into a specific directory. This is done by passing Integer.MAX_VALUE as the 'depth' argument to Files.find.
There are times when we** don't want to compile the entire tree into a single directory so it would be useful to be able to specify whether or not to recurse (depth = Integer.MAX_VALUE) or not (depth = 1).
** I need this for some tests I'm developing for Nestmates (JEP 181) and it will be simpler to fix this separately in mainline.
Testing: - check locally that test using CompilerUtils still pass. - mach5 jdk/hs tier1 and 2 Thanks, David
