EOFException: null when using postgresql and stolon

Question

We are getting this error:

Caused by: org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.
    at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:327)
    at org.postgresql.jdbc.PgStatement.executeInternal(PgStatement.java:428)
    at org.postgresql.jdbc.PgStatement.execute(PgStatement.java:354)
    at org.postgresql.jdbc.PgPreparedStatement.executeWithFlags(PgPreparedStatement.java:169)
    at org.postgresql.jdbc.PgPreparedStatement.executeQuery(PgPreparedStatement.java:117)

    at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:300)
    ... 22 common frames omitted

The query is a prepared statement with a simple SELECT with 4 arguments. Then executeQuery is called, I get the error above. The error only happens when using stolon, if we use PostgreSQL directly, everything works as expected.

Anyone faced a similar situation?

I had the same trace in another context: I fixed it updating the postgresql jdbc driver.
