jspc task error

[Edson Alves Pereira]

  Hello folks, i�ve just create this snapshot:

        <!--///////////////////////////////////////////////////////-->
        <target name="compilarPaginasJSP"
                depends="compilarProjeto">
                <jspc   srcdir          ="${src}/jsp"
                        destdir         ="${webapp}/jsp"
                        verbose         ="9"
                        package ="org.apache.jsp"
                        classpathref    ="base-path">
                        <webapp basedir="${src}"/>
                </jspc>                                         
        </target>
        <!--///////////////////////////////////////////////////////-->

  And the code above produces this error:

compilarPaginasJSP:
     [jspc] Compiling 26 source filesD:\tmp\osctrl-app\jsp\org\apache\jsp

  [jasperc]     at org.apache.jasper.JspC.main(JspC.java:823)


  If i write this in my terminal, every thing goes right.

$java org.apache.jasper.JspC -dd /tmp/osctrl-app/jsp -p org.apache.jsp
-webapp /usr/local/apachegroup/tomcat4.1.24/webapps/osctrl-app -compile

  Any idea? Is this a bug? Should I take its code and fixed?

  Best regards,
