There is an memory leak in mariadb client, version 1.2.0 which is latest

As you can see in the image which is attached,there is an memory leak in mariadb module.
Actually 5 part, which are mentioned below, are linked to memory leak.
1)org.mariadb.jdbc.MySQLStatement$1
2)org.mariadb.jdbc.internal.common.query.parameters.ParameterHolder
3)org.mariadb.jdbc.MySQLPreparedStatement
4)org.mariadb.jdbc.internal.common.query.MySQLParameterizedQuery
5)org.mariadb.jdbc.internal.common.query.parameters.LongParameter

When I figured out it, I have checked about some kinds of mistakes in my code. But, I could not find out any kinds of mistake to take place the memory leak.
In addition to that I checked mysql client, and there is no memory leak.
so I think there is some memory leak in mariadb java client.
