KSP2 default annotation KClass values for built-in types use java.lang.* versions

[ZacSweers]

Consider this example:

annotation class ExampleAnnotation(val value: KClass<*> = String::class)

@ExampleAnnotation(String::class)
class Example

In KSP2, the default value of value is a KSTypeImpl that points at java/lang/String while the KSAnnotation argument from the annotated Example class points at kotlin/String. This results in the types not being considered equal.

This was tested on 2.0.0-1.0.22-SNAPSHOT today

can you share how you configure to run on snapshot? I tried to run your test locally with a local build and I got this error

e: file:///var/folders/l7/39bc4svn2g3b08k7jx3rsf1c00m1r6/T/junit6026606767842928735/ksp/sources/kotlin/test/TestSmokeTestClass.kt:20:29 Unresolved reference 'kotlin'.

Just pushed a branch with it to the mentioned PR above: square/kotlinpoet#1885

The test is TestProcessorTest.removeDefaultValues

You can breakpoint Annotations.kt at line 59 or the isDefaultValue function on line 83 to see what I linked in the screenshots
