Re: ozone 0.4 available -- ... now error on first createObject call


Looks like I can't get past the "ojvm Local" step without running into
the NullPointerException.  But note that the WizardStore "recovering"
[info] message is not there:

G:\ozone4\samples\simple>javac Local.java
  (I modified the code to make the path "c:/tmp/db" then recompiled)
  (c:/tmp/db already has a db at 0 with one user marek id=104)
  (java is Sun jdk java2 jdk1.3RC1)

here is what happens when I do it my way, starting ozone remotely:
