JPS나 visualvm에서 thinkfree office는 나열되지만 이름이 무시된다.
이유는 JPS 문서에 나온다.

The jps command uses the java launcher to find the class name and arguments passed to the main method. If the target JVM is started with a custom launcher, the class name (or JAR file name) and the arguments to the main method will not be available. In this case, the jps command will output the string Unknown for the class name or JAR file name and for the arguments to the main method.
