A nice cross-locale same-width DateTime.toString()?
by Weijun Wang 25 Apr '12

25 Apr '12

Hi All We have a command line tool that needs to print out date/time in a table. The current Date.toString() always has the same width and it's beautiful: 76 Tue Nov 10 08:57:54 CST 2009 bin/vbin/go 1149 Sun Apr 08 16:03:20 CST 2012 bin/vbin/netbeans 170 Fri Nov 20 16:47:42 CST 2009 bin/vbin/syncdown 671 Wed Feb 08 20:11:22 CST 2012 bin/vbin/ssh.desktop 187 Fri Nov 20 16:47:34 CST 2009 bin/vbin/syncsf However, both the DOW and MON are English and might make non-English users unhappy. On the other hand, DateFormat.getDateTimeInstance() knows about locale but the output is not the same width. 76 Nov 10, 2009 8:57:54 AM bin/vbin/go 1149 Apr 8, 2012 4:03:20 PM bin/vbin/netbeans 170 Nov 20, 2009 4:47:42 PM bin/vbin/syncdown 671 Feb 8, 2012 8:11:22 PM bin/vbin/ssh.desktop 187 Nov 20, 2009 4:47:34 PM bin/vbin/syncsf or when -Duser.language=fr 76 10 nov. 2009 08:57:54 bin/vbin/go 1149 8 avr. 2012 16:03:20 bin/vbin/netbeans 170 20 nov. 2009 16:47:42 bin/vbin/syncdown 671 8 févr. 2012 20:11:22 bin/vbin/ssh.desktop 187 20 nov. 2009 16:47:34 bin/vbin/syncsf Is there a nice way to make the output same width and locale aware? I can wait for JDK 8. Thanks Max

Code Review Request: 7160242: (prefs) Preferences.remove(null) does not throw NPE [macosx]
by Kurchi Subhra Hazra 25 Apr '12

Hi, This change inserts a null check for the key being passed to Preferences.remove() on Mac, so that the method throws a NullPointerException when key is null (according to its specification). Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7160242 Webrev: http://cr.openjdk.java.net/~khazra/7160242/webrev.00/ Thanks, Kurchi

Please review: 7151434: java -jar -XX crashes java launcher
by Kumar Srinivasan 24 Apr '12

Hi, Could you please review this, actually the launcher is a 2 line change, but when I was testing/experimenting with this, it was hard to inspect the .jtr file for test failure, the test framework is cleanup to help the reader quickly identify the failing test cases. http://cr.openjdk.java.net/~ksrini/7151434 Thanks Kumar

Port to HP Itanium OpenVMS
by Josef Stadelmann 24 Apr '12

24 Apr '12

Hi all, I am absolute new on OpenJDK forum. Intention: start a port to OpenVMS Itanium Question: which project has to be ported first, given that OpenVMS has a JDK 1.6.0_05 but does not have JDK 1.7.0_* Reason: It is unclear since Months, what HP's JAVA OpenVMS Roadmap will be. But we need to know where we have to go. Fact: Annotaions like @Requestwrapper or @Responsewrapper or @Addressing, used in Web Service Java Code i.e. Apache Axis2/JAXWS support, are having demand on JDK 7.0 / 8.0 which is not available for HP OpenVMS. Hence we can use Annotations only very limitted. Question 1: Where shall I start reading on OpenJDK? Question 2: Which OpenJDK project needs to be ported first to get on OpenVMS $ JAVA.EXE running? (i.e. executing i.e. older byte code) Any hints and redirections to the proper group / project / mailing list is very welcome. Josef.Stadelmann @axa-winterthur.ch
