Delete SPV file and resync button does not work

[jmeemiller]

Platform: Bisq client 0.6.1, Java 8 update 131, Windows 7 64-bit Service Pack 1

When you click on the "Delete SPV file and resync" button under "Settings->Network Info", it displays an error dialogue (see attached) and fails to delete the file.

No message is added to the bisq.log file when clicking the button.

It also reproducible by me on Win7 every time but without any log records, silently. Occured in NetworkServiceView:249:

        reSyncSPVChainButton.setOnAction(event -> {
            if (walletsSetup.reSyncSPVChain()) {
                new Popup<>().feedback(Res.get("settings.net.reSyncSPVSuccess"))
                        .useShutDownButton()
                        .actionButtonText(Res.get("shared.shutDown"))
                        .onAction(() -> {
                            preferences.setResyncSpvRequested(true);
                            UserThread.runAfter(BisqApp.shutDownHandler::run, 100, TimeUnit.MILLISECONDS);
                        })
                        .hideCloseButton()
                        .show();
            } else {
>>>                new Popup<>().error(Res.get("settings.net.reSyncSPVFailed")).show();
            }
        });

The problem is the SPV chain file is locked by Windows:

    public boolean reSyncSPVChain() {
        try {
>>>            return new File(walletDir, SPV_CHAIN_FILE_NAME).delete();
        } catch (Throwable t) {
            log.error(t.toString());
            t.printStackTrace();
            return false;
        }
    }

delete method simply returns false. Looks like it locked by bitcoinj library in SPVBlockStorage class.

After bisq-network/support#61, I wanted to click on "Delete SPV file and resync" button under "Settings->Network Info" as asked and had the same error than @jmeemiller mentioned.

There doesnt seem to have anything in the log. Let me know if I can provide additional informations.

I just fixed that for the 0.6.5 release which got deployed just now.
