OutOfMemoryError due to LineEndingsPolicy in JvmLocalCache

[jhonnen]

I'm seeing sporadic OutOfMemoryErrors caused by the data retained in JvmLocalCache:

The large retention is caused by Gradle internal objects referenced by the line endings policy:

Gradle 8.6 with enabled configuration cache
Spotless Gradle 6.25.0
Windows 11

The large retention is caused by Gradle internal objects referenced by the line endings policy:

More specifically, it's the captured FormatExtension in the provider's lambda, so the following hack seems to work around that:

tasks.withType(SpotlessTask).configureEach {
    def fixedProvider = provider(LineEnding.UNIX::createPolicy)
    doFirst {
        setLineEndingsPolicy(fixedProvider)
    }
}

(setupTask is configured in afterEvaluate, so I needed to override the policy during execution time)

the captured FormatExtension seems to be a regression introduced by #1777
