PostgreSQL JDBC error: Missing or erroneous pg_hba.conf file

I get this error only when coming in from the local host! Remote clients,
oddly enough, don't have this problem.

Something unusual has occured to cause the driver to fail. Please report
this exception: java.sql.SQLException: Missing or erroneous pg_hba.conf
file, see postmaster log for details       at postgresql.Driver.connect(Driver.java:125)       at
java.sql.DriverManager.getConnection(DriverManager.java:453)      at
java.sql.DriverManager.getConnection(DriverManager.java:133)      at
com.exodus.change.util.DBTest.<init>(DBTest.java:28)      at com.exodus.change.util.DBTest.main(DBTest.java:44)
 

The pg_hba.conf file:

host         all         127.0.0.1     255.255.255.255   trust
host         all         203.216.99.58 255.255.255.255   trust
host         all         203.216.99.58                   trust
host         all         203.216.0.0   255.255.255.0     trust

Any ideas?
