Subject Re: Why is yum pulling in open JDK ?
Date Mon, 07 Jul 2014 16:29:12 GMT
The current RPM spec actually has a dependency on "java", which is not a
package--rather, it is a piece of metadata called "provides" that multiple
packages can share.  For example, Oracle's JVM, OpenJDK, ICedTea, etc.--can
all be used to fulfill the requirement for "java".

There is a reverse-engineered RPM spec of the DSE RPM spec here:
http://pastie.org/pastes/5191311/text

Relevant section:

Requires:      java >= 1.6.0

tl;dr: The Oracle JVM is not readily available, and so the DSE RPM uses
whichever package that satisfies the dependency "java >= 1.6.0".
