- Update to r306764.
- Generate distfiles directly from pkg-plist. This list was compiled from
running "ktrace -i -tn make" on openjdk6 and openjdk7 ports.
- Re-add jre/bin/java to work around a bug in openjdk7 build infrastructure.
It is not really necessary but langtools fails to build without it because
langtools/make/tools/GenStubs/GenStubs.java executes it based on java.home
property, which points to jre subdirectory. Note this problem only exists
on recent jdk7 langtools and jdk6 and jdk8 are not affected.
Feature safe: yes
