Request for backport of JDK-8144501

[Robert Lichtenberger]

We are currently experience null pointer problems that have their root 
cause in https://bugs.openjdk.java.net/browse/JDK-8144501.

The attached example demonstrates the problem: Click the first row, then 
Ctrl-Click the second row, then Ctrl-Click (i.e. deselect) the first row.

Up to jdk1.8.0_51 the output was (correct):
1Doe
1
---

but from jdk1.8.0_60 on the output is:
null
1
---

jdk-9-ea+116_linux-x64_bin.tar.gz shows correct output again.

Is there a way to backport the fixes (from 
http://hg.openjdk.java.net/openjfx/9-dev/rt/rev/9b7e677b5314)?

Best regards,
Robert
