Slave UUID in replica for gh-ost shows java.lang.ArrayIndexOutOfBoundsException

While using v.1.1.5 (due to compatibility issues of gh-ost's latest version with MySQL 5.7) everything runs fine, but we noticed, after issuing a

```show slave hosts ;```

command in the replica gh-ost uses to read the binlog, that the "Slave_UUID" column shows an error message rather than a proper value

```
Server_id 99999
Host ip-10-0-0-113.ec2.internal
Port 3306
Master_id 1778116519
Slave_UUID
java.lang.ArrayIndexOutOfBoundsException: Index 49 out of bounds for length 49

```

Is this a known issue that is fixed in newer versions? Or maybe a DBMS issue rather than a gh-ost issue?

Again, migrations run fine, we've moved several tables and around 700M rows with no issues so far.

We're using AWS RDS, our setup is as follows:

Master cluster, hosting the master writer and 3 Aurora read replicas
binglog format is MIXED
Engine is 5.7.mysql_aurora.2.11.3
5.7.12-log

Replica cluster, set up manually to replicate via binlog from the master writer, only 1 writer
binlog format is ROW
filtering is OFF (0)
Engine is 5.7.mysql_aurora.2.11.3
5.7.12-log

I'll gladly give more info on the issue if needed.
