The method "check" checks that an MBean implementation must be from 
"com.sun.management.internal", so even we look for an MXBean with its 
standard MXBean class (java.lang.management.*), do "check" still needs 
jdk.management module to be present.

We need more unit tests for the case when jdk.management is absent.

Thanks,
