There was only one test case under the folder "jdk/internal/util" which was jdk/internal/util/jar/VersionedStream.java.

This test case has removed by JDK-8189611.

So whenever we run the test group jdk_util_other, we will get this error message "TEST.groups: group jdk_util_other: file not found: jdk/internal/util"
