The Makefile Java example source code

#
# Makefile to run jtreg and other tests
#

# Product builds and langtools builds
#
# A full product build (or "control" build) creates a complete JDK image.
# To test a product build, set TESTJAVA to the path for the image.
#
# A langtools build just builds the langtools components of a JDK.
# To test a langtools build, set TESTJAVA to the path for a recent JDK
# build, and set TESTBOOTCLASSPATH to the compiled langtools classes --
# for example build/classes or dist/lib/classes.jar.

# JPRT
# JPRT may invoke this Makefile directly, as part of a langtools build,
# or indirectly, via FOREST/test/Makefile, as part of a control build.
