# Parse an asset file name and echo "JAVA_VERSION|OS|ARCH|EXT".
# Exits non-zero when the name does not match, so the caller can skip the asset
# instead of silently producing metadata with empty fields.
#
# Handles both naming schemes seen so far:
# graalvm-community-jdk-17.0.7_linux-x64_bin.tar.gz -> 17.0.7
# graalvm-community-jdk-21.0.2_macos-aarch64_bin.tar.gz -> 21.0.2
# graalvm-community-jdk-25i3-25.0.4.1_windows-x64_bin.zip -> 25.0.4.1
#
# The middle part between "jdk-" and "_<os>-<arch>" is treated as an opaque
# blob; the Java version is the trailing dotted-numeric run inside it. That way
# extra stream labels (25i3, and whatever comes next) do not break parsing, and
# version numbers with any number of components are accepted.
