[JasperReports compilation using wrong temp directory]

Howdy

I'm using the JasperReports library version 4.5.1 in my Java application, and I'm trying to upgrade to version 4.6.0.

I am using the JasperReports ant task to build our *.jrxml files into *.jasper files at compile time. Here is the relevant excerpt from our build.xml file:

<target name="compile-report" depends="init">    <taskdef name="jrc" classname="net.sf.jasperreports.ant.JRAntCompileTask" classpath="${javac.classpath}"/>    <mkdir dir="${build.classes.dir}/usda/weru/weps/reports"/>     <jrc tempdir="${build.classes.dir}/usda/weru/weps/reports"         compiler="usda.weru.weps.reports.compile.JRJavacCompiler"         destdir="${build.classes.dir}/usda/weru/weps/reports">        <src>            <fileset dir="${basedir}/reports">                <include name="**/*.jrxml"/>                               </fileset>        </src>        <classpath path="${run.classpath}"/>    </jrc>       <!--copy the styles into the classpath-->    <copy todir="${build.classes.dir}/usda/weru/weps/reports">        <fileset dir="${basedir}/reports">            <include name="**/*.jrtx"/>        </fileset>               </copy></target>[/code]

Note that we are using a custom implementation of the JRJavacCompiler, but it is not the problem.

Upgrading the library to 4.6.0 yields the following exception:

Error saving expressions class file : C:Program FilesNetBeans 8.0_harvestsdetail_1417022482708_967062.java

My question is this: Why is JasperReports trying to save anything in C:Program FilesNetBeans 8.0? I specify a temp directory in the ant task, why does it not use that location?

Here is the full text of the exception stack trace:
