Hi,
Recently I proposed and pushed a change for [1] which adds
--enable-preview option to javac compilation of JMH microbenchmarks in
general to enable running a benchmark that uses preview feature
(Records). This makes the class files produced marked with version
60.65535. The benchmark that uses preview feature executes without
problems because it explicitly specifies the following in its code:
@Fork(value = 1, warmups = 0, jvmArgsAppend = "--enable-preview")
Recently I wanted to run JMH benchmarks for Stream ops with:
make test TEST="micro:java.util.stream.ops"
...but all of them fail to run with the following exception:
java.lang.UnsupportedClassVersionError: Preview features are not enabled
for
org/openjdk/bench/java/util/stream/ops/value/generated/NoneMatchShort_seq_start_jmhTest
(class file version 60.65535). Try running with '--enable-preview'
What shall we do? Add similar annotation to all of them? Is there a way
to specify that all micro benchmarks should be run with --enable-preview
option passed to java?
