-----------------------------------

             Summary: HttpConduit.handleResponseOnWorkqueue will always handle response on current thread when allowCurrentThread is false and the work queue rejects the execution
                 Key: CXF-7881
                 URL: https://issues.apache.org/jira/browse/CXF-7881
             Project: CXF
          Issue Type: Bug
          Components: Transports
    Affects Versions: 3.2.6
            Reporter: Jan Hallonsten


Creating this Jira according to the discussion [here|http://example.com/]

In the method 

[org.apache.cxf.transport.http.HTTPConduit.handleResponseOnWorkqueue(boolean allowCurrentThread, boolean forceWQ)|https://github.com/apache/cxf/blob/540bb76f6f3d3d23944c566905f9f395c6f86b79/rt/transports/http/src/main/java/org/apache/cxf/transport/http/HTTPConduit.java#L1190]

If the work queue is full so that RejectedExecutionException is thrown and allowCurrentThread is false like when called from [AsyncHttpConduit|https://github.com/apache/cxf/blob/6db38f9984b9c0bf6309a3d7e26d5a9ab8055d1f/rt/transports/http-hc/src/main/java/org/apache/cxf/transport/http/asyncclient/AsyncHTTPConduit.java#L600] the expression in the if statement below will always return false and the response will be handled on the current thread via the call to handleResponseInternal. When used from AsyncHttpConduit this will be the IO core thread which is not a good idea.
{code:java}
} catch (RejectedExecutionException rex) {
    if (allowCurrentThread
        && policy != null
        && policy.isSetAsyncExecuteTimeoutRejection()
        && policy.isAsyncExecuteTimeoutRejection()) {
        throw rex;
    }
    if (!hasLoggedAsyncWarning) {
        LOG.warning("EXECUTOR_FULL_WARNING");
        hasLoggedAsyncWarning = true;
    }
    LOG.fine("EXECUTOR_FULL");
    handleResponseInternal();
}
{code}
