Description
While trying out the `kafka-assigner` command with the JMX sizer, it tried to load `/export/apps/jdk/JDK-1_8_0_72/jre/lib/amd64/server/libjvm.so`, which obviously does not exist in my system. It should attempt to find the path for `libjvm.so` from the `JAVA_HOME` environment variable instead, if the `libjvm` property is not set.

Research direction
Start with the `kafka-assigner` command and its JMX sizer code, then inspect how the `libjvm` property currently selects a library path. Confirm that an unset property uses `JAVA_HOME` to locate `libjvm.so`, while an explicitly set property remains supported.
