I am using ecj and I checked the build.xml and it does include the
properties ${boot.javac.source} and ${boot.javac.target} and I tried
changing the build.properties as I think they were set at Java 6 compliance.
I will recheck this and try your suggestions.

The thing I was confused about is that the ant-diagnostics.log showed the
system Java being used. But, I guess the rearranged JDK we use is more for
the bootstrapping process.
