             Summary: Java HTTP adapter crashes JVM when leading master disconnects.
                 Key: MESOS-7728
                 URL: https://issues.apache.org/jira/browse/MESOS-7728
             Project: Mesos
          Issue Type: Bug
          Components: java api
    Affects Versions: 1.3.0, 1.2.1, 1.1.2
            Reporter: Alexander Rukletsov
            Assignee: Alexander Rukletsov


When a Java scheduler using HTTP v0-v1 adapter loses the leading Mesos master, {{V0ToV1AdapterProcess::disconnected()}} is invoked, which in turn invokes Java scheduler [code via JNI|https://github.com/apache/mesos/blob/87c38b9e2bc5b1030a071ddf0aab69db70d64781/src/java/jni/org_apache_mesos_v1_scheduler_V0Mesos.cpp#L446]. This call uses the wrong object, {{jmesos}} instead of {{jscheduler}}, which crashes JVM:
