I fix it by deleting downloaded blockchain and restart bitcoinj app.
But this is too ugly everytime downloading blockchain not good idea...

I didn't try DiskBlockStore for a long time, perhaps I should remove it. Let's 
get you up and running with SPVBlockStore.

Did you erase the file first? It uses a different file format to 
BoundedOverheadBlockStore.

sorry , seems like problem fixed.
The problem because file was DiskBlockStore format.
But you can delete inside code and remake better maybe if broken?

Maybe we can add some more robustness around file format types, but deleting 
and rebuilding requires co-ordination with the wallet currently. It's up to the 
app. That's why it's an exception.
