WARNING: package sun.security.action not in java.base

I'm on Mac and can't add a new imagery layer, probably due to the same problem:

Error getting layers: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

[gaben]

I removed the java.base/sun.security.action=ALL-UNNAMED exports from the code, buildscripts and runtime params locally, and the warning disappeared. Not sure if it breaks anything, but JOSM seems to work just like before.

There are some hardening updates in java24 and java25.
