Bug#283557: java-common: JAVA POLICY: define defaultJAVA_HOME=/usr/lib/java as alternative.
Hi,
the program which needed JAVA_HOME was 'ant'; it might have had to do with
the fact that I had the JDK and JRE packages both installed with some
alternatives (java) pointing to the JRE and some (javac) to the JDK.
But, anyway, I had to define JAVA_HOME to make it work.
And I thought that what I proposed is aligned with the policy rule you are
listing (and which I considered in my thoughts). If /usr/lib/java is
defined as the default alternative for the JAVA_HOME directory, I can, in
my program, script, Makefile, rule-file, set JAVA_HOME to the default
/usr/lib/java value, giving the user a chance to overrule this through his
own definition of JAVA_HOME.
Am I clear? :-) I am not saying JAVA_HOME should be set to /usr/lib/java,
I am saying that /usr/lib/java could be created as alternative to be used
as default value for JAVA_HOME within programs.
But if you think that my configuration is broken, and ant shouldn't need
JAVA_HOME, then I'll try to fix it myself. Actually I think I already
fixed it by removing the JRE and re-linking the different alternatives to
the JDK (but I don't notice because JAVA_HOME is defined in my Makefile).
