In a sessioned connection, when executing:

g.tx().commit();
g.close();

Logged are the messages (empty lines added for readability):

{code}
When closing the connection directly, i.e. calling just g.close() without
calling first g.tx().commit(), then "Unrecognized content of the 'gremlin'
argument in the request" is not reported. Maybe g.tx().commit() alters the
connection's status so the 'gremlin' parameter is not provided in g.close()
> IllegalStateException: Unrecognized content of the 'gremlin' argument... on
