I dont see any visual change with this fix and it solves `get/setMinimumSize` 
contract. 
However,
I think the suggestion is to update the javadoc for JScrollBar but it does not 
have `setMinimumSize/setMaximumSize` method which has the contract in 
`JComponent.setMinimumSize/setMaximumSize` 
" Subsequent calls to getMaximumSize will always return this value;"

so not sure where to update the spec..in the JScrollBar class top summary or in 
`getMinimumSize/getMaximumSize` but since the contract is in set method, not 
sure if it will be considered if updated in get methods..
