----------------------------------------
Case 1 (using Ernie's reproducer)
On using the reproducer provided by Ernie (jsmanage2.html), the first inbound
attach frame has a target address of /$management like here -
{noformat}
[0x7ffbb4011230]:0 <- @attach(18) [name="ed3e3cb1-f719-4d97-91c3-4d00db5ce802",
handle=0, role=false, target=@target(41) [address="/$management"],
initial-delivery-count=0]
{noformat}
Notice above that the target address on the link is set to /$management. Also,
the address on the message "to" field is set to amqp:/_topo/0/QDR.B/$management
Case 2 (using qdmanage)
Now, when I used the qdmanage tool to do a QUERY operation, I am seeing that
the first inbound attach frame has a target address of
_topo/0/QDR.B/$management like here -
{noformat}
[0xaaa720]:0 <- @attach(18)
[name="38bb9314-055e-4485-927d-481250be534e-_topo/0/QDR.B/$management",
handle=0, role=false, snd-settle-mode=2, rcv-settle-mode=0, source=@source(40)
[durable=0, timeout=0, dynamic=false], target=@target(41)
[address="_topo/0/QDR.B/$management", durable=0, timeout=0, dynamic=false],
initial-delivery-count=0]
{noformat}
Note here that the target address on the link is set to
_topo/0/QDR.B/$management (and not to /$management like in Case 1)
According to Ted Ross -
Pre-merge, the router only looked at the link target address if there was no
address in the message. Post-merge, the link target address, if present,
always takes precedence over an address in the message. The post-merge
behavior is the correct behavior.
To fix this issue, the javascript needs to be modified to exactly do what
qdmanage is doing, namely create a link with a target address of
_topo/0/QDR.B/$management and send the QUERY request over the link.
