I see what the code is doing, but haven't delved into the module system details to understand exactly the rationale for these tests. In any case, filed the RFE JDK-8257856: "Make ClassFileVersionsTest.java robust to JDK version updates."

There was a change to JVMS 4.7.25 in Java 10 to add a rule for the requires_flags that are allowed. This is why this test started was created to test 53.0 vs. 54.0 class files. It wasn't intended to be a burden to update at each release so I'll re-implement it.
