Add a "-location" option to jcmd VM.classes which will show the URL of the class if possible. e.g.
769483: KlassAddr Size State Flags ClassName 0x0000000055040400 71 fully_initialized W MyApp$1 "file:///my/progs/" 0x0000000055040000 67 fully_initialized W MyApp "file:///my/progs/" 0x0000000055005800 73 fully_initialized W jdk.internal.event.ThreadSleepEvent 0x0000000055005400 73 allocated jdk.internal.event.ThreadSleepEvent ... (Fixing a column width for the ClassName seems impossible as it can be really long, so URL is simply printed after ClassName.) This is a continuation of https://git.openjdk.org/jdk/pull/29048 which was pretty far along and this is a simple import. A few minor changes in help text, (C), and of course whitespace. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - tweak help output - 8327246: Add a jcmd diagnostic command to list Class origin URLs where possible Changes: https://git.openjdk.org/jdk/pull/31420/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31420&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8327246 Stats: 120 lines in 6 files changed: 83 ins; 11 del; 26 mod Patch: https://git.openjdk.org/jdk/pull/31420.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31420/head:pull/31420 PR: https://git.openjdk.org/jdk/pull/31420
