is this a javac bug or some error in my code

When I run my Ant script, I get the following error

  compile-src:
     [echo] Source include pattern                = **/*.java
     [echo] Source exclude pattern                =

BUILD FAILED

I'm not sure what is going on, I can compile this project outside ant (in eclipse) without an issue.

I'm almost sure that the message about a bug in the compiler is a red herring, I suspect the real problem has to do with the message:

[javac] java.lang.AssertionError: {rawtypes}

but there isn't much information to help tracking down the root cause of the error.

Any ideas?

Given your compiler is really old and not publicly supported, I would assume that upgrading your JDK would be a good starting place.

The last free version of Java 5.0 is update 22 (you have update 9). http://www.oracle.com/technetwork/java/javase/downloads/index-jdk5-jsp-142662.html

The latest version of Java is Java 6 update 26. http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html

It clearly says that it is a compiler bug:

An exception has occurred in the compiler (1.5.0_09). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.

As Peter said, first check if the same problem occurs in a newer javac version, and then file a bug report. (You might try to minimize down your code to an SSCEE first.)

Eclipse does not use javac, but has its own compiler included, thus this does not tell us anything here.
