Hi Team,
Sometimes we have problem in Artemis management console on one of the test
servers. When I try to list consumers, I get an error:
could not invoke list sessionsjava.lang.IllegalArgumentException : Comparison
method violates its general contract!
Currently there are a lot of sessions and consumers, and I cannot find out
which consumer (maybe misconfigured application) causes problem.
When I invoke listAllConsumersAsJSON() method, it's output does not contain IDs
which are used for sorting by default in the sessions pane of the management
console.
For example, there are a lot of "consumerID":0, some "consumerID":1119, 1125 in
JSON output, and I wonder where does management console get long IDs like
283887157811, 283887157891 and vice versa.
How can I determine which client causes this problem?
When I get this error in management console, in the debug console it looks like:
Uncaught TypeError: Cannot read properties of undefined (reading
'selectParentNode')
at Array.onError (eval at globalEval (lib-e53c220218.js:1:2794),
<anonymous>:327:30)
at lib-e53c220218.js:1:1858073

at l (lib-e53c220218.js:1:75611)
at XMLHttpRequest.<anonymous> (lib-e53c220218.js:1:79170)
Lines 325-328 in the debugger look like:
function onError(response) {
Core.notification("error", "could not invoke list sessions" +
response.error);
$scope.workspace.selectParentNode();
};
It appears in versions 2.31.0, 2.30.0, 2.28.0 (maybe also in earlier versions).
