------------------------------------------------------------
Yes, this will work for now, at least until Java versions go past {{"99"}}.
This {{SystemUtils}} method:
{code:java}
static boolean isJavaVersionMatch(final String version, final String
versionPrefix) {
if (version == null) {
return false;
}
return version.startsWith(versionPrefix);
}
{code}
will not do the right thing when comparing {{"100"}} with {{"10"}}.

> NPE from SystemUtils.isJavaVersionAtLeast under Java 11 EA
> ----------------------------------------------------------
>
> Key: LANG-1384
> URL: https://issues.apache.org/jira/browse/LANG-1384
> Project: Commons Lang
> Issue Type: Bug
> Affects Versions: 3.7
> Environment: Java 11 EA
> Reporter: Ian Young
> Priority: Major
>
> Calling, for example,
> {{SystemUtils.isJavaVersionAtLeast(JavaVersion.JAVA_1_7);}} under the Java 11
> early access release causes a NPE:
> {code:java}
> java.lang.NullPointerException
> at
> org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast(SystemUtils.java:1654)
> {code}
> This is:
> {code}
> return JAVA_SPECIFICATION_VERSION_AS_ENUM.atLeast(requiredVersion);
> {code}
> ... 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.
> {code}
> $ java -version
> java version "11-ea" 2018-09-18
> Java(TM) SE Runtime Environment 18.9 (build 11-ea+2)
> Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11-ea+2, mixed mode){code}
