because in GridCacheContext.java:1446 tryint to read from cacheCfg local variable, but cacheCfg was zeroed out while cache stopping.
Probability of such error will be significantly lowered if in GridDhtLockFuture.LockTimeoutObject.onTimeout we pass actual value of nodeStopping flag (GridGhtLockFuture:1133) instead of hardcoded false.
