Here is that webrev: http://cr.openjdk.java.net/~jrose/7023639/webrev.jdk.00/ These are the changes to JDK code that accompany the JVM changes already under review. There are 2900 LOC deleted, and 7000 LOC added. Key changes: - method handle behavior is fully represented by LambdaForm objects - chained method handles (including "adapter method handles") are gone - an ASM-based bytecode spinner compiles LambdaForms when they warm up - bound method handles are compactly represented without boxing - the private symbol-resolution interface to the JVM (MemberName) is improved - unit tests have more systematic coverage - a number of minor bugs are fixed This is implementation work. No public Java APIs are changed, although the javadoc is slightly edited for clarity. Please have a look. — John _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
