| 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. | |
| 5 | |
| 6 It cannot be run automatically because of the need for the older version of javah | |
| 7 to compare against. | |
| 8 | |
| 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. | |
| 13 | |
| 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. |
