Jan Lahoda has updated the pull request incrementally with one additional commit since the last revision: Improving Class.getPermittedSubclasses to filter out permitted classes that are not a subtype of the current class, and other adjustments per the review feedback. ------------- Changes: - all: https://git.openjdk.java.net/jdk/pull/1483/files - new: https://git.openjdk.java.net/jdk/pull/1483/files/4d484179..ff1abf06 Webrevs: - full: https://webrevs.openjdk.java.net/?repo=jdk&pr=1483&range=02 - incr: https://webrevs.openjdk.java.net/?repo=jdk&pr=1483&range=01-02 Stats: 250 lines in 8 files changed: 217 ins; 14 del; 19 mod Patch: https://git.openjdk.java.net/jdk/pull/1483.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1483/head:pull/1483 PR: https://git.openjdk.java.net/jdk/pull/1483
