Messages delivered from HttpTunnelServlet connected broker are limited to 64K bytes.

• Key: AMQ-1308
• Type: Bug

• Fix Version/s: NEEDS_REVIEWED

Description

In TextWireFormat.java: the methods writeUTF/readUTF are used in the code path to deliver messages from an HTTP connected broker.

public void marshal(Object command, DataOutput out) throws IOException { out.writeUTF(marshalText(command)); }

public Object unmarshal(DataInput in) throws IOException { String text = in.readUTF(); return unmarshalText(text); }

These methods limit the max message size to 64K. Messages sent to an HTTP connected broker do not have the same limitation.

Problem first reported in activemq-users with the subject "UTFDataFormatException in broker when using a http transportConnector".

THanks,
