3 This directory contains a program for comparing the output of new javah against the
4 output of JDK 6 or other older versions of javah.
6 It cannot be run automatically because of the need for the older version of javah
7 to compare against.
9 The test works by scanning a jar file, such as rt.jar, looking for all files with
10 native methods. It then runs both the old and new versions of javah on those
11 classes with native methods, and verifies that the results are character-for-character
12 identical.
14 To run the test, build langtools, then execute the script in the root langtools
15 directory, providing the location of the JDK to be tested. The default is
16 /opt/jdk/1.6.0.
