The binaries that AdoptOpenJDK produces have passed the full OpenJDK test suite and other tests (donated by the community) ensuring a good quality binary. However, they are not JCK/TCK compliant. If you want a formally (JCK/TCK) tested and verified Java binary then you can get one from a commercial vendor.
