Description
Implementation of JDK-8280389 Classfile API JEP
Comments
Historical note: the Classfile implementation depends on JEP 441 (Pattern Matching for Switch) which was a Preview feature at the time this was integrated. Therefore, this change includes several adjustments to allow preview languages features to be used from within the JDK. Since that time, JEP 441 has been integrated as a non-preview feature. Thus, these adjustments have been reversed, and preview language features are no longer allowed to be used in the JDK. This was done by JDK-8308093.
