As reported by Serkan: When I put an order in the wholesale market for an amount with a non-numeric price (can be any string or NaN, Inf), then my cash position is delivered as "NaN" and no longer come back to normal. A small problem, but may happen.
The limitPrice field of Order is a Double, so arbitrary strings are not possible. Updated getLimitPrice() to return null if value is NaN, log error if constructor called with limitPrice = NaN. Deployed in 1.4.3-SNAPSHOT.
