# Install jtreg 7.4 and add to PATH.
#
# NOTE: While upgrading jdk version, if this jtreg version does not build
# openjdk correctly, try using a recent version of jtreg that does work.
#
# ALSO NOTE: The installed location of the JDK is annoyingly path dependant,
# and is "/usr/lib/jvm/java-21-openjdk-amd64" on x86_64 but "-aarch64" on
# ARM64. The `build.sh` step below uses a wildcard to work around the fact that
# we don't know the full path.
