Description of problem:

If you create a POJO in Data Modeler and specify New Package, for example:

org.redHat

Data Modeler will transform this package name into lower case, producing output
org.redhat

This is not desired as in Java, case sensitivity *matters*.

Version-Release number of selected component (if applicable):

How reproducible:
always

Steps to Reproduce:
1. Create new object in data modeler
2. specify new package org.redHat
3. save

Actual results:
package name is converted to lower case

Expected results:

package name is left as inputted, i.e. org.redHat remains org.redHat
Additional info:
How I have discovered it? I have deployed a WebService which accepted object org.redHat.Person in one of its method. I wanted to configure WebService task in the Process Web Designer, so first, I have created object Person in Data Modeler, and put it in the org.redHat package. Then I have configured WS to use this object as a parameter. During the web service invocation I have received a missmatch error because org.redhat.Person is not the same as org.redHat.Person
