Question on paths ref Java

The LibreOffice Portable FAQ says that :
"jPortable, the portable Java runtime, can be installed in one of two locations:

* X:\PortableApps\CommonFiles\Java (Highly Recommended as other apps can use it)*
* with LibreOffice Portable installed to X:\PortableApps\LibreOfficePortable
... "

Does this mean that, if I have LibreOffice Portable installed in :
C:\_My\Apps\PrtPACom\LibreOfficePortable

then it will automatically find jPortable in :
C:\_My\Apps\PrtPACom\CommonFiles\Java

I guess what I am asking is, does it look for java based off a relative path from the LibreOfficePortable directory, or is it hard-wired to an absolute path and hence an assumed location in the complete directory tree ?
