jlink fails due to unexpected hash of java.* modules

[Sebastian Stenzel]

Basically the same bug as I reported earlier in https://bugs.launchpad.net/ubuntu/+source/openjdk-14/+bug/1868699, however it also affects the latest LTS build:

/usr/lib/jvm/java-11-openjdk-amd64/bin/jlink \
> --output myRuntimeImage \
> --no-header-files \
> --no-man-pages \
> --strip-debug \
> --compress=2 \
> --verbose \
> --add-modules java.base,java.logging,java.xml,java.sql,java.management,java.security.sasl,java.naming,java.datatransfer,java.security.jgss,java.rmi,java.scripting,java.prefs,java.desktop,jdk.security.auth,jdk.unsupported,java.net.http,jdk.crypto.ec
Error: Hash of java.rmi (ccefd4d0a51f66cd65f3b648c4a74a67202a3069035b27038b32b26ab601ce8b) differs to expected hash (e5f988d0fe0cb2e35b244771b92cadab4df78eae2cbfc7c60de8cddcbaec5025) recorded in java.base

I'm not sure, if bugs on the openjdk-14 package are even seen by anyone, so I decided to re-report this here.

This build of OpenJDK tampers with the jmods without fixing the hashes, making the new packaging tools useless for PPAs.

I also asked in the openjdk mailing list and they suggested that this is probably caused by patches applied by Ubuntu's builds https://mail.openjdk.java.net/pipermail/jigsaw-dev/2020-March/014398.html

[Francivan Bezerra (fba-rio)]

I can confirm the issue on OpenJDK 11, 13 and 14 on Ubuntu 20.04 LTS. I had to download a build from the OpenJDK website.
