i2psnark errors - java.lang.StringIndexOutOfBoundsException: String index out of range: -1

Hi,

I just started up i2psnark standalone, running with i2pd through I2CP.
I am seeing these errors in the console output:

Upon checking the Java I2P router logs, I see the same messages.

Fixed in 78b4598b4c2281566f48e24e5f93a3460fcaf51f 0.9.26-8

Caused by not verifying that announce URL contained a path, i.e. not the invalid ​http://example.i2p - these will now be rejected.

This could have come in a torrent file (although your log shows it happened on two different torrents) or a bad announce URL configured manually. Some sort of i2pd-only or i2cp-only corruption seems less likely.

I'm running many torrents which do not use a tracker, they are running solely on DHT.

On a different router with similar torrents, there are a large number of these errors too and with unique strings at the end of the "Thread terminated unexpectedly: TrackerClient?" line.

Thanks for the fix.

Fix tested and confirmed to be good.
