Error message

TPC100500011

What it means

MqMessage.buildMessage throws ErrorCodeEnum.TPC100500011 when the message body cannot be converted to bytes using the platform default charset (UnsupportedEncodingException from RemotingHelper.DEFAULT_CHARSET). It indicates an internal charset problem while assembling the RocketMQ message.

Solutions

1. Check the JVM's file.encoding / default charset; run with a standard value like -Dfile.encoding=UTF-8.
2. Verify RemotingHelper.DEFAULT_CHARSET resolves to a supported charset name (UTF-8) in your environment.
3. Log the exception (already done) to confirm which charset name failed, and rebuild/fix the runtime image if the charset is missing.

Example fix

// before
java -Dfile.encoding=ISO-8859-x -jar app.jar
// after
java -Dfile.encoding=UTF-8 -jar app.jar

// ensure charset support at startup
if (!Charset.isSupported("UTF-8")) {
    throw new IllegalStateException("JVM does not support UTF-8");
}

try {
    Message msg = MqMessage.buildMessage(body, topic, tag, key);
} catch (BusinessException e) {
    log.error("MQ message charset failure: {}", e.getMessage(), e);
}

When it happens

Trigger: Calling MqMessage.buildMessage (via checkMessage) where body.getBytes(RemotingHelper.DEFAULT_CHARSET) throws UnsupportedEncodingException — practically only when the JVM does not support the configured default charset name.

Common situations: JVM started with an unusual -Dfile.encoding value on a minimal JRE lacking that charset, a broken/custom RemotingHelper constant, or running on a stripped-down runtime image.
