Remedy

For versions 1.1 to 1.9.14 and 1.10.0 to 1.10.7, set the java.io.tmpdir system property to a private directory-- only readable and writable by the current user-- before running Ant. For versions 1.9.15 and 1.10.8, use the Ant property ant.tmpfile instead. Ant 1.10.8 protects the temporary files if the underlying filesystem allows it, but using a private temporary directory is still recommended.

Remedy

Set the java.io.tmpdir property of the JVM to point to a directory that is not world read/writable.
