Regression introduced with 9341bf3d "java: when
rethrowing, store the original exception," but these two appear to be the only
two cases related to com.sun.star.lang.WrappedTarget[Runtime]Exception in that
patch that would now create bad UNO Any values.  Happily reverted to the
original but oddly inconsistent setting of the WrappedTargetException's
TargetException member...
