Dear MonetDB users, I would like to access my MonetDB (latest version: v1.7 (Jul2015-SP1)) database through JDBC (MonetDB JDBC driver version 2.18) using IntelliJ IDEA 15.0 under Mac OS X 10.9.5. The "Test connection" function succeeds, but the "Refresh" function crashes in the Database tool of the IDE with the Exception below. The same problem happened when I was trying to connect to PostgreSQL 9.4 with a PostgreSQL JDBC driver older than JDBC version 4.2. I guess that MonetDB's JDBC driver has JDBC version 4.0 only. Any ideas on how to fix this? Best regards, Endre Palatinus ===== Exception: ====== TABLE_TYPE unavailable java.lang.NullPointerException at nl.cwi.monetdb.jdbc.MonetResultSet.getObject(MonetResultSet.java:1945) at
