* To fix https://github.com/halcyon/asdf-java/issues/46 and https://github.com/halcyon/asdf-java/issues/57 added the jvm_impl after the vendor if it's not the hotspot jvm
* Only openj9 is special case, hotspot and graalvm should be ignored
* Suppress grep output, but show message about what is found. In case the test fails this helps to see what part broke.
* Added testcase for the graalvm-graalvm I accidentally introduced, so this won't happen in the future
* Add support for aarch64
* Add ARM64 build to Travis CI build matrix
* Add JDK data for aarch64
* Add support for armv7l
* Add JDK data for armv7l/arm32-vfp-hflt
* Use `arm64` (Apple M1 on Darwin) as alias for `aarch64`
