> Updates the thread dump generated by HotSpotDiagnosticMXBean.dumpThreads and > jcmd Thread.dump_to_file to include thread state and lock information. Also > update the HotSpotDiagnosticMXBean.dumpThreads API description to link to a > description of the JSON format dump as that format is intended to be > parseable/read by tools. > > This PR is dependent on > [pull/25425](https://github.com/openjdk/jdk/pull/25425). As noted in that PR, > the changes accumulated in the loom repo, and have been split up to make it > easier to review. > > The changes include some re-implementation of ThreadDumper. This is because > it used PrintStream and didn't fail if there was an I/O error, e.g. file > system full. Furthermore, the indentation to pretty print the json was > fragile and hard to maintain so this is changed to use a supporting writer > class to do this. > > Test coverage is significantly expanded, including updating the test library > that is used by several tests to parse the thread dump. > > Testing: tier1-6
