The reason is that the machine lacks the openjdk-debuginfo package. Note that the package version must be the same as the jdk version.

I couldn't find this package from the yum source, so I found one
http://debuginfo.centos.org/6/x86_64/java-1.8.0-openjdk-debuginfo-1.8.0.161-3.b14.el6_9.x86_64.rpm

Or find it from the following website

http://debuginfo.centos.org/6/x86_64/ 

Download the rpm package to the server locally and install it manually

rpm -ivh java-1.8.0-openjdk-debuginfo-1.8.0.161-3.b14.el6_9.x86_64.rpm
