Richard N. Hillegas commented on DERBY-7126: -------------------------------------------- I may have figured out how to simulate the old behavior. I took the regenerated jar file and replaced the emc class with the corrupted version from the old corrupted jar. Then I replaced the old corrupted jar with the result. The result is a hacked jar which does not match its modern certificate. The test now runs cleanly on JDK 18 and JDK 11. But I am still confused about the value of the JDK 18 behavior and the value of Derby's support for signed jars. > Make it possible to build and test Derby cleanly with OpenJDK 18 > ---------------------------------------------------------------- > > Key: DERBY-7126 > URL: https://issues.apache.org/jira/browse/DERBY-7126 > Project: Derby > Issue Type: Task > Components: Build tools > Affects Versions: 10.16.0.0 > Reporter: Richard N. Hillegas > Assignee: Richard N. Hillegas > Priority: Major > Attachments: DERBY_7126_A.java > > > Releases of Open JDK 18 can be found at https://jdk.java.net/178.
