Alessio Soldano commented on CXF-6811:
--------------------------------------
I would actually suggest removing that method, as it does not seem to be used
anywhere in Apache CXF sources and from a user point of view it does not add a
lot on top of a basic System.getProperty("java.version") .
> org.apache.cxf.common.util.ClassHelper.getJavaVersion() method will fail on
> JDK9

> Key: CXF-6811
> URL: https://issues.apache.org/jira/browse/CXF-6811
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.1.5
> Reporter: Richard Opalka
>
> JDK9 will come with new versioning scheme, see:
> http://openjdk.java.net/jeps/223
> We identified the following snippet of code to be problematic for JDK9
> adoption:
> org.apache.cxf.common.util.ClassHelper
> {code}
> public static double getJavaVersion() {
> String version = System.getProperty("java.version");
> return Double.parseDouble(version.substring(0, 3));
> }
> {code}
> ATM this code fails on:
> Exception in thread "main" java.lang.NumberFormatException: For input string:
> "9-e"
> at
> jdk.internal.math.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:2054)
> at
> jdk.internal.math.FloatingDecimal.parseDouble(FloatingDecimal.java:110)
> at java.lang.Double.parseDouble(Double.java:539)
> at
> org.apache.cxf.common.util.ClassHelper.getJavaVersion(ClassHelper.java:90)
> with Early access JDK9.
> Once official JDK9 is released this code will fail on
> StringIndexOutOfBoundsException.
