JNI calls the add function of List in Java to flit back
New changes to the problem

The problem
Flash back code is as follows:
in recent applications, the need to transfer data in C to Java a structure, in this structure, there are GNSSObservation object type of List, GNSSObservation for custom structures, therefore in the jni invocation List are required for data transmission of the add function to add data into the List, but the program, when the function is called multiple times, flash back, specific code is as follows:

env – & gt; CallObjectMethod(GnssObservationList,GnssObservationListAddFunctionID,GnssObservation); Instead of running every time, the program runs for several minutes in a row, and the function is called about 40 times per second. The reason for the backout is never found, and the data that needs to be passed to Java is passed as a double array. The reason for the code flash back has not been solved, I hope you can give some suggestions on the cause of flash back.
