It is not an attractive situation, but while awkward can easily be best. The Responder must know that Opener can be under pressure and making a jumpshift on a short suit. Thus, a Responder should never jump to 5 of a minor with only 4 trumps. For example if the auction went: 1S-1NT 3C-? A responder holding 8 A876 K765 10876 can raise to 4C, and if the Opener rebids 4S the Responder should let the contract play in Spades. In the hand you mentioned A4 AQ10 6 KQJ10965, it is tempting to jump to 2H. However, a jumpshift into a 3-card major is very dangerous, as Responder may easily bury you. A 3C with this hand is clearly an underbid, so my personal preference would be to bid 3NT. While 3NT is slightly mis-descriptive (It promises a better suit), it takes pressure off the Responder when 3NT is right. If slam is there, Responder can still bid again.

You might do more in the area of responding to the JS by opener. I strongly encourage the use of the rebid of openers first suit as a waiting bid when you do not really have anythign to say, so opener can complete the descrition of his hand. Robinson wrote that up in Washington Standard. An excellent write up! You might do more in the area of responding to the JS by opener.
