@magicus you wrote the original patch. Do you have any idea why the make is failing with:


Building target 'default (exploded-image)' in configuration 'macos-aarch64'
make[3]: *** No rule to make target `/Users/gadams/jdk11u-dev/build/macos-aarch64/buildtools/langtools_tools_classes/_the.BUILD_TOOLS_LANGTOOLS.vardeps', needed by `/Users/gadams/jdk11u-dev/build/macos-aarch64/buildtools/langtools_tools_classes/_the.BUILD_TOOLS_LANGTOOLS_batch'.  Stop.
