RFR : 7185965 Build error in javadoc make stage for bundles not containing crypto package

[Seán Coffey]

Similar to 7163470, the JDK has historically allowed builds without the 
javax.crypto package src.

In such cases a jce.jar bootstrap should be used where necessary. One 
remaining use case is during javadoc building process. Simple fix and 
I've verified with a test build of docs.
