> Please review this partial backport of [JDK-8225810](https://bugs.openjdk.java.net/browse/JDK-8225810) which fixes an issue of returning an incorrect type name for lambda classes. The type name includes a `.` where it should be a `/`. This causes an issue for debuginfo generation in native-image (from Mandrel, which is based on OpenJDK 11u). A regression test for this follows with [JDK-8270184](https://bugs.openjdk.java.net/browse/JDK-8270184).
