This bug is also not found in JDK 1.3.

HP would like a fix for Solaris Reference 1.2.2._00next



//Program Name TnoScroll.java
// Sun BUG: How to Duplicate the Problem:
//
//Problem:HP chart defect number JAGad76398
//If AWT TextArea gains focus via TAB, it does not display the key
//pressed. Upon a mouseEntered, it will correctly display the key.
//This is broken in Solaris JDK 1.2.2_009
//and is fixed in the prelim build of JDK 1.2.2._010
//It is fixed in Solaris 1.3.
//
//To duplicate, use TnoScroll.java;
//1. The application screen has text fields and text area
//2. Some text is typed in the TextArea on the right.
//3. Click on the textfield to the left of the textarea (That has the text) and press "Tab" key
//so that the focus comes on the textarea and the text written in
//the textarea is selected but mouse-cursor is still on the
//textfield.
//4. Press any key -- it will not display (eg. Press
//"Delete" and it does not delete the selected characters.
//5. Bring the mouse-cursor anywhere in the textarea and then press
//"Delete/Backspace" key. It works.
