Research on memory leakage in Java application

The problem of memory leakage in Java applications is researched in this paper. Our purpose is to find out the instances where the memory leak appears and to put forward the solutions to avoid it. Although the Garbage Collection (GC) mechanism can be regarded as the special Java function to release objects automatically by the garbage collector, the problem of memory leakage still exists in Java applications frequently. In this paper, the leakage problem is researched from memory mechanism of JVM, and some experiments are done in accordance with the way of memory access in Java. At last, the causes of memory leakage are classified and analyzed, and then the solutions to avoid this problem are proposed.
