+++ This bug was initially created as a clone of Bug #1217108 +++

When running the migration tool shipped by BPMS 6.1 against repository generated by BRMS 5.2, the following issue occurs:

*********************************************************************************
In 5.2, any rule that uses a java.util.Date produces the following line in the .rdrl file:
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("dd-MMM-yyyy");

During migration, however, the line is transformed to an invalid form that will throw exceptions at runtime:
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("null");

If I save the file via the 6.1 UI, the SimpleDateFormat line no longer exists in the rule. Since we have over a hundred projects, that is not necessarily a valid option.
*********************************************************************************

This bz is a split from bug 1216173 where all of the supporting attachments could be found.

The migration tool had been tested to migrate from BRMS 5.3.

The bpms migration guide [1] doesn't say the migration tool only works for 5.3.

It says it works for migration from brms 5 to bpms 6.1.

Do you think this is going to be a problem? Are there any known issues for migrating from 5.2 to 6.x?

thanks.
