Bug#1108573: kotlin: FTBFS with default Java 25

[Vladimir Petko]

Dear Maintainers,

The package fails to build due to two issues. Kotlin vendors the
JavaVersion class from intellij-idea-community, which cannot parse 25
as a valid Java version. Kapt3 plugin in Kotlin depends on
com.sun.tools API had a breaking change.

I have raised MR[1] in intellij-community-idea with an upstream patch
to fix Java version parsing.
I have raised MR[2] in Kotlin to rebuild it against the updated
intellij-community-idea and apply the kapt3 patch[2].

Would it be possible to consider those MRs as a solution for this issue?

Best regards,
Vladimir.
