[bug#40387] [PATCH] gnu: Set JAVA_HOME for all Java development kits.

[Pierre Neidhardt]

* gnu/packages/java.scm (icedtea-6, icedtea-7, openjdk9)[native-search-paths]:
  Set JAVA_HOME to "jre".
  This fixes issues for which the Java tooling could not find Jars,
  e.g. tools.jar.

Is your /tmp a separate partition, and full at the time this build fails?

/tmp is a separate partition but it's a tmpfs, it uses my virtual
memory which is largely free (5GiB+).

Which tools have you observed not to work? I tried running javac and I
got the help output at least.

Thanks,

Sorry, I forgot, I've moved on since then.
Maybe it was for some Clojure thing.
