FULL PRODUCT VERSION :
java version "1.8.0_101"

ADDITIONAL OS VERSION INFORMATION :
Linux blue 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2+deb8u2 (2016-06-25) x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
https://docs.oracle.com/javase/8/docs/technotes/guides/deploy/javafx_ant_task_reference.html#CIAIEJHG describes a JavaFX Ant task for specifying application details—namely, fx:info. However, including the JavaFX Ant tasks in a project (as specified by https://docs.oracle.com/javase/8/docs/technotes/guides/deploy/javafx_ant_tasks.html#CIAEIAGE ) does not define the fx:info task.

Apparently, this occurs because the com/sun/javafx/tools/ant/antlib.xml entry in the lib/ant-javafx.jar file that is part of the JDK does not define the "info" task.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In an Ant build file, use <taskdef> to include the tasks defined in ant-javafx.jar. Execute a target which makes use of <fx:info>.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect all Ant tasks described in the JavaFX Ant Task Reference, including fx:info, to be available to my Ant build, when I import them from lib/ant-javafx.jar.
ACTUAL -
fx:info is not defined. Ant produces an error stating that the “info” task does not exist.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Problem: failed to create task or type javafx:com.sun.javafx.tools.ant:info
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

The definitions in the namespace javafx:com.sun.javafx.tools.ant are:
    deploy
    resources
    fileset
    signjar
    preferences
    jar
    permissions
    csstobin
    platform
    init-ant
    application


REPRODUCIBILITY :
This bug can be reproduced always.
