i would try to reorder the maven dependencies, so postgresql part is
loaded first.
or like other people with same error, try exclude postgis-stubs from
postgis-jdbc:
|<dependency>
||<groupId>org.postgis</groupId>
||<artifactId>postgis-jdbc</artifactId>
||<version>1.3.3</version>
||<scope>compile</scope>
||<exclusions>
||<exclusion>
||<groupId>org.postgis</groupId>
||<artifactId>postgis-stubs</artifactId>
||</exclusion>
||</exclusions>
||</dependency>|
