Description
Change in 1.4.2-beta Javah results in Apache Ant (1.5+) <javah> task failing. I understand that the Javah API is not public but its still going to burn Java developers.

Comments
If this is still an issue and the fix is low risk then let's to it in 8, else defer to 9.    If it is no longer an issue, close it.

This refers to "old old javah" and is no longer an issue.  Both javah and ant have moved on since then
2013-04-26 
WORK AROUND

Call javah using the <exec> ant task.

EVALUATION

Unlikely to be addressed in 1.4.2.  Ant will have to check what
version JDK it is running on and use a method present on that JDK.

Perhaps in 1.5 we can piggyback on JSR 199 and provide a supported
API for javah.
