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

From: Pierre Neidhardt <[email-masked]>
Date: Thu, 2 Apr 2020 10:10:17 +0200

* 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.
