I've recently updated my GWT project to 2.6.1, and started to make use of Java 7 syntax since 2.6 now supports Java 7.
However, when I attempt to compile, I'm receiving compiler errors such as
[ERROR] Line 42: '<>' operator is not allowed for source level below 1.7

How do I specify the GWT compiler to target 1.7? I was under the impression that it would do that by default, but I guess not. I've attempted cleaning the project, including deleting the gwt-unitCache directory but to no avail.
Here is my Ant compile target.
<target name="compile" depends="prepare">
<javac includeantruntime="false"
debug="on"
debuglevel="lines,vars,source"
srcdir="${src.dir}"
destdir="${build.dir}"
source="7"
target="7">
<classpath refid="project.classpath"/>
</javac>
</target>
<target name="gwt-compile" depends="compile">
<java failonerror="true" fork="true" classname="com.google.gwt.dev.Compiler">
<classpath>
<!-- src dir is added to ensure the module.xml file(s) are on the classpath -->
<pathelement location="${src.dir}"/>
<pathelement location="${build.dir}"/>
<path refid="project.classpath"/>
</classpath>
<jvmarg value="-Xmx256M"/>
<arg value="-sourceLevel"/><arg value="7"/>
<arg value="${gwt.module.name}"/>
</java>
</target>
