EJB Attachment protocol mismatch -------------------------------- Key: WFLY-7564 URL: https://issues.jboss.org/browse/WFLY-7564 Project: WildFly Issue Type: Bug Components: EJB Reporter: David Lloyd Assignee: David Lloyd Priority: Blocker Fix For: 11.0.0.Alpha1 In both EJB client and server code, on method invocations where context data is sent, the sender writes the attachment count as a packed integer but the reader consumes it as an unsigned byte. This is not good. The fix: * In protocol 3 and higher, always read and write a packed integer * In protocol 2 and lower, always read a packed integer but write a signed byte, failing if more than 127 attachments are present Note that this is only temporary in the WFLY project as the server code should ultimately be moving to live in the ejb-client library.
