Added modules -- jdk.unsupported for the above, now it has the following exception.

jdk.unsupported is a required module, I'm glad you found that. There is some discussion of this in #273 that might offer clues. Maybe you need another flag? That thread also mentions --add-exports java.base/sun.nio.ch=ALL-UNNAMED.

Hi @ben-manes , many thanks for your kind response, tried to pass this as jvm arguement,

The exception remains same,

Sorry but I can’t help, this is not directly caused by this library.

I’d try on AdoptJdk instead of a customized distribution. If that fails, then ask for help from your local build’s author. That error isn’t normal and from your environment.

May I know the recommended spring boot version for Caffeine 2.8.6. I tested with 2.2.2

[ben-manes]

Spring uses a BOM for the version that they have verified against. Our latest is backwards compatible with all Spring versions (1.4+) that offer support.
