Thanks.
Tried bitcoinj, but failed miserably
After executing this code:
./wallet-tool dump --dump-privkeys --wallet=[path to my wallet] > wallet.txt
I got an empty file wallet.txt and the following error:

Although I was able to extract the seed with wallet-decrypt, I'm wondering what went wrong here.
