[8u] RFR: 4949105: Access Bridge lacks html tags parsing

[Alex Kashchenko]

Hi,

Please review the backport of JDK-4949105 to 8u:

Bug: https://bugs.openjdk.java.net/browse/JDK-4949105

Original review thread: 
http://mail.openjdk.java.net/pipermail/swing-dev/2019-September/009793.html

11u changeset: 
https://hg.openjdk.java.net/jdk-updates/jdk11u/rev/628d3e224aaa

8u webrev: http://cr.openjdk.java.net/~akasko/jdk8u/4949105/webrev.00/

8u specific changes: paths, copyright year, String.strip() replaced with 
trim().

On the strip() change: while trim() and strip() are not equivalent 
(details: https://bugs.openjdk.java.net/browse/JDK-8200378 ), trim() may 
be appropriate here for 8u.
