Description

Our JNI libraries for MesosSchedulerDriver, v0Mesos and v1Mesos all use weak global references to the underlying Java objects, but they incorrectly state that this will prevent JVM from GC'ing it. We need to fix these coments.

e.g., https://github.com/apache/mesos/blob/master/src/java/jni/org_apache_mesos_v1_scheduler_V1Mesos.cpp#L213

 

See the JNI spec for details: https://docs.oracle.com/javase/7/docs/technotes/guides/jni/spec/functions.html#weak
