java.lang.IllegalArgumentException: Class name mismatch: io.vertx.ext.sync.Sync

[JuKu]

Hi,

I get an unexpected exception, if i use fiber handler in event bus and awaitResult().

getEventBus().consumer(eventName, Sync.fiberHandler((Message<ApiRequest> event) -> {
    //...

    //execute sql query to list rows of table
    List<JsonObject> rows = database.listRows("SELECT * FROM `" + database.getTableName("group_members") + "` WHERE `userID` = '" + userID + "'; ");//this line throws the exception

    //...
}

method Database::listRows():

@Override
public List<JsonObject> listRows (String sql) {
    ResultSet rs = awaitResult(h -> this.connection.query(sql, h));

    //get rows as list
    List<JsonObject> rows = rs.getRows();

    return rows;
}

Full exception:
