NPE when generating benchmark code

[Mark Price]

Hi Aleksey,
thanks for the response.

ant version is 1.9.2
java version is 1.6.0_37

the ant file is embarrassingly tangled, but it boils down to:

<javac srcdir="src/test/java" destdir="build/test/classes" debug="on" fork="yes" encoding="UTF-8" target="1.6"
                   source="1.6" debuglevel="lines,source,vars" deprecation="on" includeantruntime="no" memorymaximumsize="256m">
                <compilerarg value="-Xlint:unchecked"/>
                <compilerarg value="-XDignore.symbol.file"/>
                <compilerarg value="-s"/>
                <compilerarg value="build/test/classes"/>
                <classpath>
                    <path refid="${@{module}.@{artifact}.conf.compile}-path"/>
                    <extra-classpath/>
                </classpath>
            </javac>
