WalletAppKit slow TESTNET sync when .spvchain file is removed.

[msgilligan]

I am using bitcoinj 0.17-alpha1.

If I remove the .spvchain file for a previously synced wallet and start up WalletAppKit, I get the following log output:

15:59:21.820 [NioClientManager] INFO  o.b.c.l.DownloadProgressTracker - Downloading block chain of size 2322685. This may take a while.

I am running the ConsensusJ SPV daemon on the current master branch ConsensusJ/consensusj@ed956ab.

WalletAppKit is constructed as follows:

return new WalletAppKit((BitcoinNetwork) config.network(), ScriptType.P2PKH, KeyChainGroupStructure.BIP43, dataDirectory, filePrefix);

See https://github.com/ConsensusJ/consensusj/blob/master/cj-btc-daemon/src/main/java/org/consensusj/daemon/micronaut/BitcoinFactory.java

and started with:

public void start() {
        log.info("WalletAppKitService.start()");
        kit.setUserAgent(userAgentName, appVersion);
        kit.setBlockingStartup(false);  // `false` means startup is complete when network activity begins
        kit.startAsync();
        kit.awaitRunning();
        signingService = new WalletSigningService(kit.wallet());
  }

This is testnet I assume. What's your earliest key birthdate? Is it around 2013-10-02? Use wallet-tool to examine your wallet if you aren't sure.

Yes.

What's your earliest key birthdate?

I believe it is 2019, but I'll check.
