LibreOffice with Java?

[Walter Hurry]

I note that in the Makefile for libreoffice
(/usr/ports/editors/libreoffice/Makefile) it says:

"LibreOffice works only with Java 6"

But I have Java 7. Is this a problem?

$ java -version
openjdk version "1.7.0_04"
OpenJDK Runtime Environment (build 1.7.0_04-b22)
OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode)
$

LibreOffice seems to install (from the port) and run OK.
This is 9.0-RELEASE on amd64.
