Ant “JAVA_HOME does not point to the JDK” – but it does

The real message is that Ant can’t find com.sun.tools.javac.Main.

Which, together with the fact that the latest “Sun” (Oracle) JDK is 1.7.0_13 (or maybe _14, but definitely not the “_52” that your install dir indicates), makes me think that you’re not using a distribution that Ant recognizes. You can verify this by running jar tvf $JAVA_HOME/lib/tools.jar, and looking for that class.

The Ant Manual talks about ways to work with different compilers. Since I’ve only used “Sun” compilers, I’m afraid that I can’t give you any pointers.

Edit: you could also try setting fork="yes" in your build file. This should run the compiler executable rather than trying to invoke the compiler class.
