--- Comment #1 from V Stuart Foote <vstuart.foote at utsa.edu> ---
The new Java 9 release seems to work correctly on a 5.4.2.1 build.

But, as Stephen B. suggested would happen bug 100501#7, for Windows builds
LibreOffice is not finding the Java Runtime and it must be located manually
with the Add button. 

Looks like to locate the "JavaHome" string we will have to change our registry
search path in the Windows Registry [1] to match the Oracle path changes.

The JRE now uses
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JRE\9]
"JavaHome"="C:\\Program Files\\Java\\jre-9"
"RuntimeLib"="C:\\Program Files\\Java\\jre-9\\bin\\server\\jvm.dll"

While the JDK uses
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JDK\9]
"JavaHome"="C:\\Program Files\\Java\\jdk-9"

Previous builds used
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.8.0_144]
"JavaHome"="C:\\Program Files\\Java\\jre1.8.0_144"
"MicroVersion"="0"
"RuntimeLib"="C:\\Program Files\\Java\\jre1.8.0_144\\bin\\server\\jvm.dll"

and we search for the "Java Runtime Environment" for JRE or "Java Development
Kit" instead of the new JRE, JDK entries.

Also, looks like there will be no 32-bit JRE for Java 9, meaning we'll have to
continue to support the older paths indefinitely.
