RFR: 8335060: ClassCastException after JDK-8294960

Wed Jun 26 06:57:20 UTC 2024

Conversion of `java.lang.invoke` package to Class-File API is failing to execute method handles with specific type conversion requirements. Root cause is in the new `TypeConvertingMethodAdapter::primitiveTypeKindFromClass` implementation. Original code has been matching the types by hash code and it mistakenly appeared to be matching the primitive types.

This patch fixes `TypeConvertingMethodAdapter::primitiveTypeKindFromClass` and adds tests to better cover `TypeConvertingMethodAdapter` functionality.

Please review.

Thanks,
Adam
