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.
