Hello! I'm new to bitcoinj, and before doing anything, I just want to try some easy stuff. I want to read the whole blockchain from Block #1, and doing some statistics.
I have this program: https://pastebin.com/avszTeAK It doesn't suppose to do anything. The only thing it should do: just count all the blocks! When I compile my code, I always get this warning: mar. 19, 2018 10:00:04 DU org.bitcoinj.core.Context getOrCreate WARNING: Implicitly creating context. This is a migration step and this message will eventually go away. mar. 19, 2018 10:00:04 DU org.bitcoinj.core.Context <init> INFO: Creating bitcoinj 0.14.6 context. After this, it starts counting the blocks. But at Block #481815 there is always an exception. Block #481814 Block #481815 Debugging java.lang.NegativeArraySizeException at org.bitcoinj.core.Message.readBytes(Message.java:334) at org.bitcoinj.core.TransactionInput.parse(TransactionInput.java:143) at org.bitcoinj.core.Message.<init>(Message.java:96) at org.bitcoinj.core.Message.<init>(Message.java:128) at org.bitcoinj.core.ChildMessage.<init>(ChildMessage.java:57) at org.bitcoinj.core.TransactionInput.<init>(TransactionInput.java:133) at org.bitcoinj.core.Transaction.parse(Transaction.java:564) at org.bitcoinj.core.Message.<init>(Message.java:96) at org.bitcoinj.core.Message.<init>(Message.java:128) at org.bitcoinj.core.ChildMessage.<init>(ChildMessage.java:57) at org.bitcoinj.core.Transaction.<init>(Transaction.java:232) at org.bitcoinj.core.Block.parseTransactions(Block.java:242) at org.bitcoinj.core.Block.parse(Block.java:266) at org.bitcoinj.core.Message.<init>(Message.java:96) at org.bitcoinj.core.Message.<init>(Message.java:128) at org.bitcoinj.core.Block.<init>(Block.java:162) at org.bitcoinj.core.BitcoinSerializer.makeBlock(BitcoinSerializer.java:270) at org.bitcoinj.core.MessageSerializer.makeBlock(MessageSerializer.java:72) at org.bitcoinj.utils.BlockFileLoader.loadNextBlock(BlockFileLoader.java:154) at org.bitcoinj.utils.BlockFileLoader.hasNext(BlockFileLoader.java:87) at com.company.BitcoinReader.read(BitcoinReader.java:33) at com.company.BitcoinReader.main(BitcoinReader.java:68) First I downloaded the Bitcoin blockchain from here: https://getbitcoinblockchain.com/ Then I tried to solve my problem after a few failed attempts by downloading the blockchain using BitcoinCore: https://bitcoin.org/en/download Sadly it didn't solve the problem.
