Can't we use lazy initialization here? I had similar experience with
this class in the past, and think it should not be so fragile to
initialization sequence. And definitely it should not affect whole VM
run.
2006/10/18, Paulex Yang <[EMAIL PROTECTED]>:
A little further hack shows that, the cause is o.a.h.luni.util.Msg
cannot be initialized so early, which is the exception message i18n
helper class. Its static init codes try to load ResourceBundle but
failed. The new i18n helper o.a.h.l.internal.nls.Messages has same
issue. I modified the java.net.URL ln.296 as below, and the test passed.
- throw new MalformedURLException(
- org.apache.harmony.luni.util.Msg.getString(
- "K00d8", spec)); //$NON-NLS-1$
+ throw new MalformedURLException("exception message here");
