Jcr2vfs migration tool swaps DRL declared fact's package name and class name

Description of problem:

When migrating DRL assets declaring facts, Jcr2vfs migration tool imports assets into VFS repository in such a way, that the package name and class name of the asset are swapped. For instance, the class mortgages.Applicant is migrated as follows (part of VFS repo dump):

<assetWithHistory>
...
<relativePath>mortgages/src/main/resources/mortgages/mortgages.java</relativePath>
<source>package Applicant;

/**

• This class was automatically generated by the data modeler tool.
  */

public class mortgages implements java.io.Serializable {
...

I have (hopefully) tracked the breaking change to the commit [1] - look for lines such as the highlighted one - a new instance of DataObjectImpl is created, but the arguments are swapped, please see [2]. There are several occurences of this change.
