Subject: Add support for pegging the JVM version when checking code coverage.
X-Git-Url: https://jaekl.net/gitweb/?a=commitdiff_plain;ds=sidebyside;p=cfb.git

Add support for pegging the JVM version when checking code coverage.

It seems that jcov has trouble with Java 9, and has been failing since I upgraded the
system default JVM to Java 9.  This change consults JAVA_HOME for the JVM path, so that
Jenkins can override it and have a successful build.
