--- Comment #6 from Sean Cleary <seancle...@ie.ibm.com> --- An echo statement was pushed in just before the javac task for the magic property: <echo message="build.compiler: ${build.compiler}"/> and the output on Windows and Linux for Ant 1.10.11: [echo] build.compiler: org.apache.tools.ant.taskdefs.compilers.JavacExternal In case it helps, the actual 'build.compiler' property is being set in our script to that value so as a test it was unset before the javac task and compilation arguments returned correctly in the verbose output and the Java files were compiled correctly. -- You are receiving this mail because: You are the assignee for the bug.
