javac erroneously throws up rawtypes warning for use of diamond operator

Building with the latest http://hg.openjdk.java.net/jdk7/jdk7 checkout
(b94) with either OpenJDK6 or OpenJDK7 and JAVAC_MAX_WARNINGS:

summary:     6921740: Eliminate warnings from sun.io converters and
allow compiling with JAVAC_MAX_WARNINGS=true

was first applied to add these diamond operators and remove the
original raw types, javac could compile these classes successfully.
So javac seems to have regressed since then.
