Hi, The 'build-test-lib' target seems to be broken:
- make/test/BuildTestLib.gmk references the directory $(TEST_LIB_SOURCE_DIR)/sun which does not seem to exist. This can be fixed by removing the reference. - Some test-lib sources use preview-features which is not enabled by make/test/BuildTestLib.gmk. This is fixed by adding a JAVAC_FLAGS with --enable-preview and also adding 'preview' to DISABLED_WARNINGS - ASN1Formatter.annotate has a possible lossy conversion from long to int which can be fixed by adding an explicit cast Let me know if this is worth fixing and I can create a PR from this branch of fixes: https://github.com/openjdk/jdk/compare/master...eirbjo:build-test-libs Thanks, Eirik.
