OpenJDK 7 u4 and core dumped in 32bits mode

[Henri Gomez]

Hi to all,

While experimenting OpenJDK 7 u4 for OSX, in 32bits mode (-d32) with a
Jenkins server as Java app, I encountered following Java core many
times (java.text.SimpleDateFormat.format(Ljava/util/Date;Ljava/lang/StringBuffer;Ljava/text/Format$FieldDelegate;)Ljava/lang/StringBuffer)

If I select -d32 and -client, problem disappears.

Any ideas ?
