jni-test-examples

Set of god, java projects using native code, used to exercise JDK's JNI. Each run is tuned to serve as QA. It is useing ancient run-folder-as-tests. Running to long? Reduce default reruns (5) to 1: export RFAT_RERUNS=1 Want to run just subset? Set second parameter as regex, or export WHITELIST/BLACKLIST. If you would run individual test manually, export JDK_MAJOR= to numerical version of jdk. Eg 8 or 21... Such variables may multiply.

deps

lmdbjava for jdk21 and up needs zig.

[1] --add-opens to fix NativeTest.setBlocking:35 » InaccessibleObject Unable to make field private fi...
-> todo fix in upstream. Similar issue also for 17 on el7

[2] !skipped! java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer;
-> no longer fixable

[3] from forks (lmbdjava unmergable, scala hopes)

[4] !skipped! older wildfly needed for jdk8
-> todo, fix here hopefully [5] !skipped! newer wildfly needed for jdk newer then 8
-> intyetnionally jdk8 onlyu [6] this test currently fails everywhere - the goal is to investigate if there is any environemnt where it can pass
-> s!skipped! klnown to fail on newer ubuntu/fedora

On top of that:

el9 and up

• Excluded wildfly8-openssl

el7

• Excluded jnr-posix SpawnTest.inputFile
• Excluded wildfly-openssl and lmdbjava

ppc64le

Excluded jnr-posix LinuxPOSIXTest.testMessageHdrMultipleControl

• jnr/jnr-posix#178
