Problem Summary: fix jvm metrics memory leak.

when you set enable_jvm_monitor=true in be.conf, you can find that be jvm memory is slowly growing. By analyzing the hprof file, we can find that there are a large number of java.lang.management.ThreadInfo objects. The specific cause of the memory leak is: jni does not manually delete the local reference after getting the object from the array, resulting in the object not being GC.
