|reference back to instance |externalizing
------- Additional Comments From tuomas.kiviaho@iki.fi 2007-03-26 23:06 -------
NPE is thrown from function mapper when externalizing second time. First time
loses reference to originating method and second time ignores the fact that
method may indeed still be null.
Patch is to prefer non-transient fields filled during externalization over
method itself.
Caused by: java.lang.NullPointerException
