Negative binlog_position

[tetnobic]

Hi !
We are receiving this error when trying to restart Maxwell:

ERROR TaskManager - cause:
com.zendesk.maxwell.schema.SchemaStoreException: com.mysql.cj.jdbc.exceptions.MysqlDataTruncation: Data truncation: Out of range value for column 'binlog_position' at row 1
  at com.zendesk.maxwell.schema.MysqlSchemaStore.processSQL(MysqlSchemaStore.java:114) ~[maxwell-1.42.3.jar:1.42.3]
  at com.zendesk.maxwell.replication.BinlogConnectorReplicator.processQueryEvent(BinlogConnectorReplicator.java:385) ~[maxwell-1.42.3.jar:1.42.3]
  at com.zendesk.maxwell.replication.BinlogConnectorReplicator.processQueryEvent(BinlogConnectorReplicator.java:407) ~[maxwell-1.42.3.jar:1.42.3]

After some investigation, it seems that the method
getPosition() of the EventHeaderV4 class returns a negative value

We've tried altering the field schemas.binlog_position from int unsigned type to int type and no more error...

Here is the dump of our schemas table :

What can we do to avoid this issue ?
Any help would be appreciated!

Perhaps needs to create an issue at https://github.com/shyiko/mysql-binlog-connector-java ?

sorry for delay, maintainer was in iceland. yeah, looks like we need to upgrade those fields to longs inside the binlog connector. bah.
