Comments
Mnemonic shortcut is intentionally not displayed in tooltip from jdk6. As per fix in JDK-5047379, HTML tooltips have been fixed such that the shortcut key/accelerator is now being painted. Additionally, it was determined that it makes no sense to show the mnemonic binding in a tooltip. Therefore, the only time we'll show an accelerator key in the tooltip is if someone has added a WHEN_IN_FOCUSED_WINDOW binding to the component's InputMap.

Checked this with JDK 5u22 and current version and could confirm the issue as reported. The mnemonic shortcut has failed to display when the cursor is moved over the button with all versions post 5u22. The tool tip is displayed as expected though. (see attached images for reference). Result: 5u22: OK 6: FAIL 6u45: FAIL 7u80: FAIL 8u131: FAIL 9 ea b175: FAIL To verify run the attached test case. This seems a regression appeared while migration from JDK 5 to 6.
