http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21761 [lang] SystemUtils.IS_OS_*, IS_JAVA_* always returns false. Summary: [lang] SystemUtils.IS_OS_*, IS_JAVA_* always returns false. Product: Commons Version: Nightly Builds Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Lang AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] SystemUtils.IS_OS_*, IS_JAVA_* always returns false. This case is on Mac OS X. ---- % java -version java version "1.4.1_01" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-39) Java HotSpot(TM) Client VM (build 1.4.1_01-14, mixed mode) ---- The test code is: --- import org.apache.commons.lang.*; public class OSNameTest { static public void main(String[] arg) { System.out.println(System.getProperty("os.name")); System.out.println(SystemUtils.IS_OS_MAC_OSX); System.out.println(SystemUtils.IS_OS_WINDOWS); System.out.println(SystemUtils.IS_JAVA_1_4); } } -- The result is: --- Mac OS X false false false --- It should be: -- Mac OS X true false true -- The cause: IS_JAVA_*, IS_OS_* values are based on JAVA_VERSOIN, OS_NAME, OS_VERSION. But JAVA_VERSION, OS_NAME, OS_VERSION are initialized after IS_JAVA_*, IS_OS_* values. When IS_OS_* are initialized, OS_NAME == null. They should be declared considering the initialization order. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
