JNLP已经初始化，与icedtea6-插件NullPointerException异常？

Question

我有一个值得信赖的小程序，而我掌握的OpenJDK和icedtea6-插件以下行为：

Initializing JVM...
NOT IMPLEMENTED: virtual nsresult IcedTeaPluginInstance::Start()
Jar string: applets/MyApplet.jar
jars length: 1
JNLPRuntime already initialized
java.lang.NullPointerException

netx: Initialization Error: Could not initialize applet. (net.sourceforge.jnlp.LaunchException Fatal: Initialization Error: A fatal error occurred while trying to verify jars.)

太阳JVM和插件工作正常。可能是什么回事？

这只是一个OpenJDK的问题。它应该被固定在最新的版本（未在回购）。
