> Parsing of Java version is done in cassandra-env.sh via

> java_ver_output=`"${JAVA:-java}" -version 2>&1`
> jvmver=`echo "$java_ver_output" | awk -F'"' 'NR==1 {print $2}'`
> {code}
> This fails if the first line of output from `java -version` does not contain
> the version. When JAVA_TOOL_OPTIONS is set as the output is
> {quote}
> Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
> java version "1.7.0_40"
> Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
> Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)
> {quote}
> Parsing this is not guaranteed to work as there is no contract for this
> output. The recommended way of dealing with this is via a Java application
> (which will have access to each of these pieces).
> If you want to keep with this model of doing things, you can apply a very
> small but hacky patch:
> {code}
> -jvmver=`echo "$java_ver_output" | awk -F'"' 'NR==1 {print $2}'`
> +jvmver=`echo "$java_ver_output" | grep 'java version' | awk -F'"' 'NR==1
> {print $2}'`
> JVM_VERSION=${jvmver%_*}
> JVM_PATCH_VERSION=${jvmver#*_}

> Otherwise, you need to write a java app, compiled for older versions, that
> returns this data via the java.specification.version and a combination of
