Version is almost always too specific - remember that some operators may wish to support a single stream of java that may change for users over time.  Someone using a java language pack may only want to support one java runtime at a time, but that version # might change.  It might be major version, it might be minor version, or the minor version might end up having major incompatible changes and thus a new stream has to be forked.

The operator needs a way to define a label for users to select a stream ("1.6") that may change over time ("1.6.5.X"), but with a unique id that links apps created against "1.6" to those created later.  The operator may also need to supply metadata for these streams, like "obsolete", "will be end of lifed soon".  An individual version of a lp in a stream will inherit / reference metadata at some point in time (created at x, has exactly version 1.6.5 build).

The user definitely needs to be able to choose a version - but that version is a choice that exists for a limited period of time.
