Please review the following: Bug: https://bugs.openjdk.java.net/browse/JDK-8154069 Patch: http://cr.openjdk.java.net/~ptbrunet/JDK-8154069/webrev.01/
The scenario is resetting a second combo box via setSelectedIndex(-1) when a first combo box changes. With the fix the selection is now cleared. jtreg for my test case and JCK for JComboBox both ran OK. 3 of 9 JPRT build jobs failed (Mac and both Windows). There is nothing about the patch that should cause a build problem on those three platforms so I assume the failures are due to some other unrelated issue. I'll check to see who might know what's going on with the JPRT builds. TiA, Pete
