IIUC, only description of the format is in the source: https://github.com/openjdk/jdk/blob/2f23c80e0de44815d26a7d541701e16c9c1d32bc/src/java.base/share/classes/sun/text/RuleBasedBreakIterator.java#L325

It's a bug in the plugin `--include-locales=*` which will read all resources from `jdk.localedata` with ASM ClassReader and the plugin just happens to work.  The plugin should only read `.class` entries or specific `LocaleDataMetaInfo` implementation classes.    I created https://bugs.openjdk.org/browse/JDK-8304367 that Naoto will help fixing.
