Subject RE: ant-1.6.5; need to add tools.jar to system classpath

Jan, Peter,

Thank you for your replies.

The goal is to put tools.jar on _system_ classpath. The -lib puts it on
core Ant classpath.

No the tools.jar is the actual one from the JDK. We need it on system
classpath to work around the class-loading bug in javadoc jdk 1.6.

Sorry I should have been clearer.

Thanks - this is good to know. It would be good to make this generic fix
in ant-1.6.5, as it makes ant.bat script consistent with ant script (as
far as LOCALCLASSPATH goes).

Yes, JAVA_HOME points to a JDK, but tools.jar is not on system
classpath, even if we add it to CLASSPATH.

The actual task that got broken is <jwsc>

It has dependency on javadoc. Our goal is to work around the bug in Ant
environment, rather than telling customers to edit their Ant files, or
editing our internal test files.

Thanks again,
