Wildfly 10 UT005024: Could not register resource change listener for caching resource manager - wildfly

Question

I'm using Wildfly 10 in standalone mode, when I start the Wildfly, I always get the following error messages. The applications deployed. I don't know what caused this error message, and where to look to figure out the root cause. Can anyone help me?
our environment is :
java.version = 1.8.0_66
java.vm.info = mixed mode
java.vm.name = Java HotSpot(TM) 64-Bit Server VM
java.vm.specification.vendor = Oracle Corporation
os.arch = sparcv9
os.name = SunOS
os.version = 5.11
path.separator = :
sun.arch.data.model = 64
The following is the stack trace:
