Hi All, Kindly review the fix for JDK9.
Bug: https://bugs.openjdk.java.net/browse/JDK-8149456 <https://bugs.openjdk.java.net/browse/JDK-8149456> Webrev: http://cr.openjdk.java.net/~arapte/manajit/8149456/webrev.00/ <http://cr.openjdk.java.net/~arapte/manajit/8149456/webrev.00/> Issue: [macosx] robot.keyPress do not generate key events (keyPressed and keyReleased) for function keys F13 to F19. Cause: robot.keyPress(keyCode) passes java key code for the particular key pressed to native side (MacOS X). On the MacOS corresponding key code matched and returned to java side. But as per the current implementation keys with java key code below 222 returns a valid key code form MacOS X and for all java key codes above 222 MacOS don’t have any valid key code to return and it returns a default value 127 (undefined) for all of them including function keys F13 to F20. The java key codes for keys F13 to F19 is in range 61440 to 61447. Fix: Create a dictionary of java keys and OS X keys with: key: java key value: OS X key Use the macros defined as macros in header java_awt_event_KeyEvent.h for java keys Define integer constants for OS X keys as shown below: const static int OSX_kVK_ANSI_A = 0x00; const static int OSX_kVK_ANSI_S = 0x01; const static int OSX_kVK_ANSI_D = 0x02; const static int OSX_kVK_ANSI_F = 0x03; Problem in modifying/extending current fix: Why the current fix can’t be extended/modified to support keys F13 to F20. 1) The current fix creates an array with array index as java key and array value as corresponding OS X key. static const unsigned char javaToMacKeyCode[] = { 127, // 0 0 VK_UNDEFINED No_Equivalent 127, // 1 0x1 Not_Used 127, // 2 0x2 Not_Used Here 0, 1 and 2 are the java keys and 127, 127 and 127 are the corresponding key values in OS X for the same key. The array can’t be modified to add support for F13 to F20 because their corresponding values are 61440 to 61447. It won’t be a good solution to extended the array with index 61440 to 61447. 2) The current fix creates an array using a pearl script. The pearl script uses hardcoded values of java keys and OS X keys. Also the Pearl script is not checked in to the java codebase. 3) The current fix not modifiable and not readable. Time comparisons between with and without fix in milliseconds: The time comparison is done by taking the time diff in milliseconds before and after calling robot keypress for all the keys using the test code written for the fix. Time diff taken for 5 test runs: With fix: 1658, 1698, 1705, 1453 and 1516 Without fix: 1523, 1579, 1690, 1648 and 1504 Note: The following java keys are not matched in the current fix because of the following reasons: 1) They are already matched with their corresponding keys on Mac OS. 2) There are no defined keys on Mac OS with the same functionality for PRINTSCREEN, SCROLL LOCK and PAUSE. 3) The following java keys are not defined in keyTable in AWTEvent.m file. java_awt_event_KeyEvent_VK_PRINTSCREEN java_awt_event_KeyEvent_VK_SCROLL_LOCK java_awt_event_KeyEvent_VK_PAUSE In the previous fix these keys were matched to OSX_F14, OSX_F13 and OSX_F15 respectively.
