      Description

      When I use toolchains and configure GraalVM as the active toolchain AND my default JDK is NOT GraalVM (JAVA_HOME != GraalVM) I'm getting NPE from surefire plugin

      Caused by: java.lang.NullPointerException

          at org.apache.maven.surefire.booter.SystemUtils.toJdkVersionFromReleaseFile (SystemUtils.java:141)

          at org.apache.maven.surefire.booter.SystemUtils.isJava9AtLeast (SystemUtils.java:215)

          at org.apache.maven.plugin.surefire.AbstractSurefireMojo.getEffectiveJvm (AbstractSurefireMojo.java:2446)

       

      It works fine when I change JAVA_HOME to point to GraalVM home.

      The reason is that https://github.com/apache/maven-surefire/blob/master/surefire-booter/src/main/java/org/apache/maven/surefire/booter/SystemUtils.java try to read JAVA_VERSION from releases file and GraalVM doesn't have this variable there.

      I'm not sure who is at fault, maybe GraalVM should export that var.
