I am running ant 1.4.1 on solaris 2.8
my question is about the javac task.
the resulting class files generated are different when using the ant [javac]
task vs. the command line javac.
one class file size is 234 bytes and the other 309.
why would this be?
i have a very simple class called Test.java and here is my build.xml:
<project name="POC" default="all" basedir=".">
<target name="ant" depends="" >
<exec executable="which">
<arg line="javac" />
</exec>
<javac srcdir="." destdir="." verbose="true"/>
<exec executable="javap">
<arg line=" -classpath . Test" />
</exec>
<exec executable="ls">
<arg line="-l Test.class" />
</exec>
</target>
<target name="javac" depends="" >
<exec executable="which">
<arg line="javac" />
</exec>
<exec executable="javac">
<arg line=" -verbose ./Test.java" />
</exec>
<exec executable="javap">
<arg line=" -classpath . Test" />
</exec>
<exec executable="ls">
<arg line="-l Test.class" />
</exec>
</target>
<target name="clean">
<delete file="./Test.class"/>
</target>
</project>
when i run
bash-2.03$ ant ant
Buildfile: build.xml

these two steps give different class sizes and javap outputs!
how could this be?
thanks!
