xip is an old archive format used to distribute XCode.  it's actually an xar format but with ability to be signed. If you installing the same software multiple times and don't want to spend time to verify known to be valid signature, instead of xip -x do the following (you can use xar -x -f instead of bsdtar xvf):

bsdtar xvf Archive.xip

ditto -x Content .

 

 

From JEP 230 - how to build and run jdk microbenchmarks using openjdk build system:

./configure  --with-jmh=/opt/jmh/target

make test-bundles

make build-microbenchmark will build build/$PROFILE/images/test/micro/benchmarks.jar

make test TEST="micro:java.lang.invoke" would run all the java.lang.invoke microbenchmarks with default settings.
