Bug reference: 1172
Operating system: Fedora core release 2
Description: JDBC driver fails to compile

Postgresql version: 7.4.3
Java: j2sdk_1.4.2_04
ant: 1.5.2-26

JDBC driver fails to compile with error:

/usr/local/src/postgresql-7.4.3/src/interfaces/jdbc/org/postgresql/jdbc3/Jd
`org.postgresql.jdbc2.optional.PoolingDataSource.getDataSource(java.lang.St
[javac] bc3PoolingDataSource.java:29: error: Method ring)' was defined
with return type `org.postgresql.jdbc2.optional.PoolingDataSource' in class
`org.postgresql.jdbc2.optional.PoolingDataSource'.
[javac] static Jdbc3PoolingDataSource getDataSource(String name)

This error message is pretty mangled, but I suspect you might have another
version of the driver somewhere on the classpath. The driver will fail
to compile in this situation as it gets confused with the
different versions of the same class.

No, my classpath is empty! I managed to compile fixing the following:
on class Jdbc3PoolingDataSource lines 29 & 31 changed
Jdbc3PoolingDataSource for PoolingDataSource.

On class Jdbc3ObjectFactory line 46 added a cast to
Jdbc3PoolingDataSource.

Taking a closer look the driver has some rather odd code there, but I get
no failure here. Is there any change you aren't really using sun's jdk to
compile this and one of the free compilers out there?
