Subject [jira] [Commented] (PROTON-844) proton-j: ArrayIndexOutOfBounds exception if remote peer sends a handle >1024
Date Thu, 02 Apr 2015 19:31:53 GMT

ASF subversion and git services commented on PROTON-844:
--------------------------------------------------------

Commit f937ccd04a99575cb44ec4108908d155e9f3a101 in qpid-proton's branch refs/heads/master
from [~dnwe]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-proton.git;h=f937ccd ]

PROTON-844: police handle-max in proton-j

* when receiving an attach with a handle > handle-max, the connection
  should be closed
* when attempting to allocate a new local handle when handle-max are
  already in-use should throw an Exception
* the default of 1024 handle-max is quite small when proton-c appears to
  default to 4294967295 - increase it more modestly to 65536

Closes #16

> If a remote peer attempts to attach with a handle >1024, its advertised handle-max,
a proton-j service will hit an ArrayIndexOutOfBoundsException in the call to getLinkFromRemoteHandle
> Similarly, if a proton-j client attempts to allocate a local handle when all 1024 are
used up, it chooses UnsignedInteger.MAX_VALUE rather than throwing an Exception locally.
