# Test on compilation and execution of Java class files.
# Also meddle with wrapper scripts, as would be probably seen in a real
# "UNIX-style" use case.
# This test uses a typical "nested" source tree setup (i.e., different
# components/aspects are separated into different subdirectories), and
# uses the parallel testsuite driver.
# The sister test 'java-compile-run-flat.sh' do similar checks with
# a "flat" setup (i.e., everything in the top-level directory), and
# forcing the use of the older 'serial-tests' driver.
