[9] Review request for 7020860: BasicTreeUI contains getters/setters with unclear spec

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-7020860

webrev: http://cr.openjdk.java.net/~ssadetsky/7020860/webrev.00/

The methods mentioned in JIRA are not getters/setters according to 
JavaBeans specs, nevertheless some of them got wrong javadocs. The 
proposed fix improves the situation.
