    A handler for treating .zip (and .jar and .tar ...) files as if they were a volume mounted at /home/user/foo.zip - e.g. https://github.com/openjdk/jdk/blob/jdk-21-ga/src/java.base/...

    It may be easier to reason about when thinking of the way $(mount -o loop) works with .iso files -- a file that is a container for other files that one can mount as if it were a filesystem

    I was expecting pathlib in Python <https://docs.python.org/3/library/pathlib.html> to have one since a lot of Python distributions ship the standard library in .zip files but evidently not. Python gonna Python in that way

    Firefox actually used to ship with that same "jar:" protocol handler, too, and I made good use of it for reading the javadoc html which was shipped inside zip files and was indescribably easier than trying to manage all the .html files in a Java 8 SDK distribution

    This comment is not correct. Java uses mixed Latin1/UTF-16 strings. The Latin1 mode is for compact storage of alphanumeric text as the name suggests, but comes at a cost of dispatch to determine the encoding when selecting subsequent handling of indexing and other operations: https://github.com/openjdk/jdk/blob/1ebf2cf639300728ffc02478...

    The MAX_PATH limit is annoying legacy backwards compatible stuff, but can be avoided by prefixing paths with \\?\ before passing them into the Windows API.

    This is something that languages/runtimes with more effort put into portability already handle for you:

    https://github.com/openjdk/jdk/blob/master/src/java.base/win...

    If Python doesn't do this it's just because the sort of people who write Python don't care about Windows enough to fix it.

    I felt out of the loop, thinking that Zero VM was some kind of new distro for OpenJDK but chasing <https://packages.debian.org/sid/openjdk-22-jre-zero#:~:text=...> to <https://sources.debian.org/src/openjdk-11/11.0.23%2B9-1/debi...> lead me to https://github.com/openjdk/jdk/tree/jdk-22-ga/src/hotspot/cp...

    It seems that it's a specific CPU target for the Hotspot JIT for non-mainstream architectures (or for research purposes, as I saw mentioned once)
