java.lang.InternalError: Pool jdk.types.StackTrace must contain at least one element

[Annette0127]

Hi! I'm currently learning how to work with JFR files and I've been trying to use this project to extract stack traces from the "Events" section of JFR files.

I've been experimenting with some JFR files generated by IntelliJ IDEA. I've been following the demo code provided in this project:

Path jfrFile = ...; // path to some-recording.jfr

Properties properties = new Properties();
properties.put("model", JfrSchemaFactory.INLINE_MODEL.formatted(jfrFile));

try (Connection connection = DriverManager.getConnection("jdbc:calcite:", properties)) {
    PreparedStatement statement = connection.prepareStatement("""
            SELECT TRUNCATE_STACKTRACE("stackTrace", 40), SUM("weight")
            FROM "JFR"."jdk.ObjectAllocationSample"
            GROUP BY TRUNCATE_STACKTRACE("stackTrace", 40)
            ORDER BY SUM("weight") DESC
            LIMIT 10
            """);

    try (ResultSet rs = statement.executeQuery()) {
        while (rs.next()) {
            System.out.println("Trace : " + rs.getString(1));
            System.out.println("Weight: " + rs.getLong(2));
        }
    }
}

but I've encountered a problem that seems a bit beyond my current level of understanding. And the issue looks like this:

This exception also occurs when I use the ./jfr print command. For context, I'm using macOS Ventura and Java 21. And it seems while parsing the "constant pool" or "N checkpoint events" (according to the bloc) part, there must be at least one constant. Since IntelliJ IDEA produced the file and is able to parse it correctly, I think the file itself should be fine.

I'm reaching out in the hopes that you might be able to offer some guidance or suggest a workaround that could help me resolve this issue. I would deeply appreciate any insights or suggestions. Thank you so much in advance for your time!😊
