Non-fatal NullPointerException and lost coins when receiving bitcoins about bitcoinj

[mikehearn]

Interesting. That line runs when there's a double spend detected:

Transaction connected = doubleSpent.outputs.get((int)input.outpoint.index).getSpentBy().parentTransaction;

Unfortunately it's quite a complicated expression (too complicated), so it's hard to
know which part was null.

But presumably you weren't intending to double spend :-) What was the exact sequence
of events that led to this? Presumably the wallet is unavailable this time too?

I promised the wallet will not be unavailable again, so here it is (-:

I did not intend to double-spend.

I tried to describe the series of events in my bug report. All tx before (received
4 btc, sent 1.5 btc, sent 2.5 btc) went well, the client reported a balance of 0 btc
after sending away the 2.5 btc (at the entry point of this bug report).

Ah, and I think you can see from the linked blockexplorer dump that tx 9d12d10f0b29239e0807744daa50b22b4079657b12a4a0fdb842abe70f6d1ec0
was indeed no double-spend.

What you see here is a false double-spend as documented in issue #430.
