Hi All,
Please review the fix for JDK 11.
Bug:
https://bugs.openjdk.java.net/browse/JDK-4334792

Issue:
Lead Index in DefaultListSelectionModel will never return to -1 in
some cases as described.
Fix:
1) JList.setSelectionIndex(-1)
The doc says JList.setSelectedIndex() should select a single cell, but
it doesn't mean it should clear selection if the argument is -1.
This will also not be fixed as this is not an issue and behavior is
expected.
2) JList.clearSelection()
The proposed fix addresses this issue.
3) ListModel.removeAllElements()/ListModel.clear
This issue has been addressed already except the case when the
lead/anchor is 0/0 and then JList.removeAllElements/ListModel.clear is
called, then the anchor/lead is not set properly. This case is
addressed in the proposed fix. This will also fix the
https://bugs.openjdk.java.net/browse/JDK-6481195
4) ListSelectionModel.setLeadSelectionIndex()
This is not an issue as lead can be set to -1 by
setLeadSelectionIndex, if the anchor is already set properly. This is
expected behavior and will not be changed.
