Classes compiled prior to the nestmate support will generate `REF_invokeSpecial` if the implementation method is a private instance method. Since a lambda proxy class is a hidden class, a nestmate of the host class, it can invoke the private implementation method but it has to use `REF_invokeVirtual` or `REF_invokeInterface`. In order to support the old classes running on the new runtime, LMF implementation adjusts the reference kind from `REF_invokeSpecial` to `REF_invokeVirtual/REF_invokeInterface`.
This PR fixes the check properly to ensure the adjustment is only made if the implementation method is private method in the host class. ------------- Commit messages: - JDK-8274848: LambdaMetaFactory::metafactory on REF_invokeSpecial impl method has incorrect behavior Changes: https://git.openjdk.java.net/jdk/pull/5901/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5901&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8274848 Stats: 379 lines in 4 files changed: 378 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/5901.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5901/head:pull/5901 PR: https://git.openjdk.java.net/jdk/pull/5901
