JarSigner cannot verify signature of ics64.jar with recent OpenJDK

Hello,

Our customer is using SSL Extender and ESOD. One of their users who recently installed Java is getting "Check Point Deployment Shell Internal Error"

Checking cshell.elg on the client I see following

INFO [global] (Log log) [General] Java vendor: Eclipse Adoptium (verion 11.0.14.1)
INFO [global] (Log log) [General] Certificate checking: Path does not chain with any of the trust anchors
INFO [global] (Log log) [Component] has_invalid_cert and has_unsigned_entry are false
INFO [global] (Log log) [Component] Verify - Returning false
INFO [global] (Log log) [Component] Failed to verify C:\Users\admin\AppData\Local\Temp\CSHELL\ics64\100001160\ics64.jar.tmp using JarSigner

Trying a bit older version, it still does not work

INFO [global] (Log log) [General] Java vendor: Eclipse Foundation (verion 11.0.12)

INFO [global] (Log log) [Component] Verify - Returning false                                                                                
INFO [global] (Log log) [Component] Failed to verify C:\Users\admin\AppData\Local\Temp\CSHELL\ics64\100001160\ics64.jar.tmp using JarSigner 

When using old Oracle OpenJDK it works fine and cshell.elg on the client shows:

INFO [global] (Log log) [General] Java vendor: Oracle Corporation (verion 11.0.2)
INFO [global] (Log log) [Component] Verify - Returning true
INFO [global] (Log log) [Component] Verified C:\Users\admin\AppData\Local\Temp\CSHELL\ics64\100001160\ics64.jar.tmp using JarSigner

What can be done so that newer versions of OpenJDK can be used? I tried latest Microsoft OpenJDK 11 too, with the same results.

Thank you

I recommend opening a TAC case, but I suspect it's because we don't support that version of OpenJDK (in which case, it'd be an RFE to support it).
