> This patch adds a `--validate` option to the jar tool which can be used to > validate a jar file that might be malformed. For instance, if a jar is a > multi-release jar, it is malformed if different versions expose different > APIs. > > The implementation is straight forward since there already exists validation > logic that is run when creating or updating a jar. This patch just exposes > that logic directly under a new command line flag. > > I've enhanced the existing ApiValidatorTest to also create malformed jars > using the zip file APIs (the jar tool does not output malformed jars) and run > them through `jar --validate`. > > Note that while the jdk's jar tool does not output malformed jars, > third-party archiving tools might, or the jar could have been manually edited. > > Some prior discussion here: > https://mail.openjdk.java.net/pipermail/core-libs-dev/2021-May/077420.html > > Testing: running jdk/tools/jar test suite locally, tier 1-3 (in progress), > manual testing.
