Use of Apache Ant 1.7 Causes Installation to Hang

MEP installation does not work with Apache Ant 1.7 releases. The installer script is designed to use the copy of Ant 1.6.5 that is built into the version of Application Server installed with MEP. You may have a release of Ant 1.7 on your system, but do not set the ANT_HOME environment variable to point to it; otherwise, MEP installation will hang.
