Hello,
This is a request to backport a JDK 8 fix into JDK 7u14: 8014924 JToolTip#setTipText() sometimes (very often) not repaints component. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8014924 The fix has already been pushed to JDK 8, as: http://hg.openjdk.java.net/jdk8/awt/jdk/rev/6261e94e9869 The code changes for JDK 7u40 are identical to the ones in JDK 8. Thank you, Alexandr.
