Description

When a tooltip is shown in the Java editor, for instance because the mouse is hovering over an error indication, pressing the Home or End keys on the keyboard scrolls the entire document all the way to the top or end, respectively instead of to the beginning or end of the current line. This is extremely disruptive, and likely very confusing to users, as it only happens in the stated situation.

A workaround is to move the mouse pointer away from the editor to close the popup after examining an error. Most users will not be able to discover this workaround, though--for myself, it took two weeks to discover the correlation between the tooltip being open and the bug occurring.

This bug seems to have been introduced in 8.2, and I just confirmed that it is still present on the new Apache NetBeans 9.0 beta release.
