Hi All,
Please review a rollback of the bug fix which caused large performance
regression for TextArea.
JDK-8226513 removes the zero component size check to layout the root
view when text component is updated by resetting the rootViewNeedsLayout
flag, but it caused textarea performance regression as rootview
initialization is triggered multiple times.
JDK-8226513 was a regression of JDK-8160246, which was again regression
of JDK-8130892, which in turn was a regression of JDK-8001470
where view's preferred size is set only when text component's height or
width is 0. This check is modified in subsequent fixes which caused more
regressions.
Proposed fix for performance regression is to roll back to original
issue and figure out why negative insets are obtained for
JEditorPane.getPreferredSize()
