sombriks commented on MCOMPILER-104:
------------------------------------
here's some realing info:
i had both jre and jdk installed.
since slackware ships not only jre but also a small script to properly
configure environment variables installing jdk (which have the same feature)
added a second java entry; basically i had something like
"/usr/lib/jdk/bin:/usr/lib/jre/bin" on my PATH. Plus that, my JAVA_HOME
(created by both packages) was pointing to /usr/lib/jdk
so, my best guess is that maven uses java executable location to figure where
is javac OR the last package installed was jre, which borked my symlink.
so don't worry guys, its seems ok, not really a but, just a very bad configured
environment.
if applicable you could just for sanity reasons try to ficgure if java and
javac will be in the same jdk; if not raise some warning or whatever.
