Need to install debuginfo package for openjdk

I am new to RHEL and I am trying to generate some heap dumps using jmap which it fails with an InvocationTargetException. It seems I need to install the debuginfo package for openjdk. I just updated openjdk by doing: yum update java-1.7.0-openjdk, but it didn't seem to have installed such pacakge. I have tried, yum install java-1.7.0-openjdk-debuginfo but then it tells me that it can't find that package.

Any advice is greatly appreciated
