Could not get body information

Error message

Could not get body information

What it means

JmsMessageInboundEvent.convertEventToString() returns the text payload for TextMessage instances. A JMSException while calling getText() is wrapped in a FlowableException with this message (note: the cause is not attached). It means the JMS provider failed while reading the message body.

Solutions

1. Check JMS connection/session health; reprocess the event from the broker with a fresh consumer.
2. Ensure body extraction happens inside the message listener callback while the session is alive.
3. Catch FlowableException around getBody() and fall back to message.toString() or a retry path.
4. Investigate the JMS provider logs for the underlying connection failure.

Example fix

// before
String body = event.getBody();

// after
String body;
try {
    body = event.getBody();
} catch (FlowableException e) {
    body = null; // schedule redelivery from the queue
    retryQueue.offer(event);
}

try {
    String body = event.getBody();
} catch (FlowableException e) {
    // no cause attached; treat as JMS read failure and redeliver
    retryService.scheduleRedelivery(event);
}

When it happens

Trigger: Calling getBody() on a JmsMessageInboundEvent wrapping a TextMessage whose getText() throws JMSException — typically due to a broken/closed JMS connection or an invalid message handle.

Common situations: Reading the body after session closure or connection failure; broker timeouts during message consumption; using messages outside their valid session context.
