The source of the problem is obviously the implementation of the
getJavaVersion function (in Utils.Java).
It does not accept Java 11 that reports its version as a two character
string "11":
/**
* Returns the main version number of the current JRE, e.g.
* 1.4 for version 1.4.2_03
*/
public static double getJavaVersion() {
String vm_version = System.getProperty("java.version");
if (vm_version == null)
return Double.NaN;
if (vm_version.startsWith("1.4.2"))
return 1.42;
else
vm_version = vm_version.substring(0, 3);
try {
return Double.parseDouble(vm_version);
} catch (Exception e) {
return Double.NaN;
}
}
I'd suggest modification of the above function so, that truncates the
string at the second point (if it exists) and then converts the string
to the number.
