NPE in SPVBlockStore.getChainHead() #374

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I've got a corrupted block chain file. However, getChainHead() throws NPE 
rather than the documented BlockStoreException. Because of this, Bitcoin Wallet 
does not try to recover from that situation.

E/AndroidRuntime(24091): java.lang.RuntimeException: Unable to create service
