A DESCRIPTION OF THE PROBLEM :
The JMX 1.2 specification states that java.util.Date is a basic type. (p. 63)
But the jconsole does not provide editing support for this basic type.
Therefore all MBean attributes of type java.util.Date are rendered as
readonly attributes regardless whether they are read/write or read-only
prohibiting editing them.

The management console should provide editors for all listed basic types.

This bug (no, its not an request for enhancement) is still present in 6.0 beta.
