Possible Issue and Solution

In order to invoke the gwt-compiler via an Ant task successfully, you will probably need to increase the maximum memory as follows:

<target name="gwt-compile" description="...">
<java classname="com.google.gwt.dev.GWTCompiler" fork="true” maxmemory="256m" failonerror="true">
<arg line="-out ${build}/www" />
<arg value="${gwt.module}" />
<classpath refid="gwt.classpath" />
</java>
</target>
