启动程序一次导致10个实例

我有一个旧的SUSE 8.1服务器，刚刚开始疯狂。

如果我一次启动一个程序： 

/usr/local/jdk1.6.0_21/bin/java -cp example-ser-0.8.jar:/usr/local/lib/java/slf4j-api-1.6.1.jar:/usr/local/lib/java/logback-core-0.9.24.jar:/usr/local/lib/java/logback-classic-0.9.24.jar:/usr/local/lib/java/jcl-over-slf4j-1.6.1.jar:/usr/local/lib/java/commons-cli-1.2.jar:/usr/local/lib/java/commons-lang-2.5.jar:/usr/local/lib/java/mysql-connector-java-5.1.13-bin.jar:/usr/local/lib/java/xBaseJ-20091203.jar:/usr/local/lib/java/Translator-0.7.0.jar:/usr/local/lib/java/antlr-3.2.jar:/usr/local/lib/java/joda-time-1.6.jar -Dlogback.configurationFile=logback-test.xml example.ser.Scanner abc12345

将会有10个实例运行（相同的用户，相同的参数），如ps ax -l | grep Scanner ps ax -l | grep Scanner ：

如果我在开始该程序的terminal，所有10个消失。 这个程序不会做任何分叉或创build任何额外的线程。 在这个问题出现之前，我也尝试了几个这个程序的老版本，现在他们也都遇到了这个问题。 这里可能会发生什么？

程序本身可能不会fork，但是classpath中提供的libs / jar可能是分叉的，我首先会尝试检查这些fork的代码。 如果失败，尝试用不同的JVM版本和/或环境执行它，看看会发生什么。
