ABSTRACT

In the Java a profiler interface such as JVM TI is provided for communication between a Java virtual machine and a profiler. The JVM specification, however, does not require an implementation of a profiler interface. Consequently the JVM without an implementation of a profiler interface cannot use a profiler with the JVM TI. For solving the problem, we propose a technique which analyzes heap usage without a profiler interface. This technique inserts codes to extract heap usage into source files in the Java. We implemented a code inserter to verify the proposed technique. We experimented with Java programs that are frequently used and opened, the experimental result presents the number of created objects, the maximum number of allocated objects, and the used pattern of the objects.
