Description

Calling, for example, SystemUtils.isJavaVersionAtLeast(JavaVersion.JAVA_1_7); under the Java 11 early access release causes a NPE:

java.lang.NullPointerException
at org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast(SystemUtils.java:1654)

This is:

return JAVA_SPECIFICATION_VERSION_AS_ENUM.atLeast(requiredVersion);

... which implies that JAVA_SPECIFICATION_VERSION_AS_ENUM hasn't been resolved properly, although it looks like the code in JavaVersion intends to return JAVA_RECENT in the case of unknown versions.

The java.specification.version system property is "11" in this environment.
