I am using H2 database in client-server mode. Server is running with version 1.3.175 and client with 1.3.168.
Everything seems working fine, but I get an exception executing some queries:
org.h2.jdbc.JdbcSQLException: General error: "java.lang.NullPointerException" [50000-175] at org.h2.message.DbException.getJdbcSQLException(DbException.java:332) at org.h2.message.DbException.get(DbException.java:161) at org.h2.message.DbException.convert(DbException.java:284) at org.h2.server.TcpServerThread.sendError(TcpServerThread.java:218) at org.h2.server.TcpServerThread.run(TcpServerThread.java:158) at java.lang.Thread.run(Unknown Source)
