Java 从运行config:property append的karaf 3.0.1中获取IllegalArgumentException和NullPointerException

我必须使用karaf3.0.1来运行一些需要更改的遗留代码。我不经常直接使用Karaf，但我通常使用更新的版本

我从存档站点安装了Karaf 3.0.1，设置了几个属性（

Karaf_OPTS

设置代理，以及

JAVA_MAX_MEM

），然后启动了Karaf

我需要运行的第一件事（根据其他人编写的设置过程）是

config:property append

命令

当我这样做时，它只打印执行命令时出错的

：java.lang.NullPointerException

，没有其他信息

我甚至只通过

config:property append--help

就可以实现这一点，所以我给它的参数没有问题

这里可能有什么问题，我可以做些什么来获取更多信息？

更新：

我现在确实想到了检查Karaf发行版中的日志文件，我确实在那里找到了NPE，所以我包括了堆栈跟踪，以及它之前的堆栈跟踪
