[jdk17u-dev] RFR: 8339280: jarsigner -verify performs cross-checking between CEN and LOC

Thu Sep 18 21:41:30 UTC 2025

Hi, this is a backport of openjdk/jdk21u-dev#2235. The backport is almost clean, except for:

* A slightly different context around `Main.java` imports
* 17u doesn't have `Resources_de.java` (changes were discarded)
* The `jarsigner.1` manpage has a slightly different format (manually adjusted to match the 17u format)

#### Related issues ("relates to" Jira issue links)

[JDK-8353299](https://bugs.openjdk.org/browse/JDK-8353299 "VerifyJarEntryName.java test fails") (openjdk/jdk at acd4da49a01760599ec4c325ff6c56f53ba5cc9c) and [JDK-8367782](https://bugs.openjdk.org/browse/JDK-8367782 "VerifyJarEntryName.java: Fix modifyJarEntryName to operate on bytes and re-introduce verifySignatureEntryName") (openjdk/jdk at TBD) were also included as part of this backport. They are test-only changes that improve the reliability and coverage of `VerifyJarEntryName.java`.

Since `test/hotspot/jtreg/runtime/cds/appcds/SignedJar.java` is not failing after the backport, [JDK-8353330](https://bugs.openjdk.org/browse/JDK-8353330 "Test runtime/cds/appcds/SignedJar.java fails in CDSHeapVerifier") was not included.

#### Testing

* Besides the `tier1` run from the [GitHub actions](https://github.com/franferrax/jdk17u-dev/actions/runs/17832135845) (all passed), I ran a regression using the following categories and individual tests:
    * `test/hotspot/jtreg/runtime/cds/appcds/SignedJar.java`
    * `test/jdk/java/security/SignedJar`
    * `test/jdk/java/util/jar`
    * `test/jdk/jdk/security/jarsigner`
    * `test/jdk/sun/security/pkcs/pkcs7`
    * `test/jdk/sun/security/tools/jarsigner`
        * Includes `VerifyJarEntryName.java`, created for this issue
    * `test/jdk/sun/security/tools/keytool`

No regressions were found against the current `master` branch (ec6528e9cf66abe34b9c293359ca11a4b550b7a8).
