The text decoder thread hangs when reading from a zip filesystem

[fge]

Code:

public final class TraceReadTest
{
    private static final Path ZIP_PATH = Paths.get("/home/fge/t.zip");
    private static final Map<String, ?> ZIPFS_ENV
        = Collections.singletonMap("readonly", "true");

    private static final String TRACE_PATH = "/trace.csv";

    public static void main(final String... args)
        throws IOException
    {
        final URI uri = URI.create("jar:" + ZIP_PATH.toUri());
        final LargeTextFactory factory = LargeTextFactory.defaultFactory();

        final TraceEventParser parser
            = Parboiled.createParser(TraceEventParser.class, 20);
        final TraceEventListListener listener = new TraceEventListListener();
        parser.register(listener);
        final EventBasedParseRunner<Void> runner
            = new EventBasedParseRunner<>(parser.traceEvents());

        try (
            final FileSystem fs = FileSystems.newFileSystem(uri, ZIPFS_ENV);
            final LargeText input = factory.load(fs.getPath(TRACE_PATH));
        ) {
            runner.run(new CharSequenceInputBuffer(input));
        }
    }
}
