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