PostgreSQL-JDBC 8.1-404 fails to compile (ecj bytecode compiler w/ gij 4.1
JDK):

This is because the driver dynamically decides what version of the driver
to build (JDBC2, JDBC3, or JDBC3 w/ generics) at runtime based on the
current JVM. You are running ant with a 1.5 JVM, but ecj's default
-source argument is 1.4, so it's trying to build 1.5 code, but
interpreting it as 1.4 code which cleary fails. Adding "source=1.5" in
the <javac> tag in build.xml fixes this, but that's not a general
solution because it clearly won't be able to build other versions. Do you
have a better solution for runtime determination or specification of the
version we should try to build.

You need to file jdbc reports on the jdbc users lists.

The ones about Class not being generic are probably just GNU classpath
lagging a bit behind the Java specs, but the abstract method errors look
like genuine bugs.
