[icedtea-web] RFC: allow icedtea-web to run with just a jre

[Jiri Vanek]

Hi!!

Just to keep in loop - This is related to https://bugzilla.redhat.com/show_bug.cgi?id=731358 and https://bugzilla.redhat.com/show_bug.cgi?id=731345

The patch itself looks ok. The only point I can see is that now there are three java paths set by configure -
--with-jdk-home can specify SYSTEM_JDK_DIR
--with-java can specify JAVA
and now --with-jre is added.

Is there really any reason why to keep all thee variables?


Best Regards J.

It should not be necessary for users of icedtea-web to install the openjdk development packages.
