[rules-users] Migrating repository data from Drools 5.0 to 5.3Final

[Michael Anstis]

The problem has existed since 5.2 and would potentially affect loading any
earlier version.

Prior to 5.2 the object model used by the guided decision table did not
hold a Pattern to which individual condition columns are bound.

The conversion code groups individual condition columns into the
appropriate group and moves the underlying column data accordingly (as
there was no guarantee columns with the same bound name were consecutive).

There was a problem with the creation and insertion of the new Pattern
objects that relied upon the order of entries in a HashMap being
consistent. This has now changed.

I know others have been using the new guided decision table with old
repositories without problem and our unit tests did not detect the problem
either.

AFAIK this is the first report of any such issue since the release of 5.2's
betas, however I would be wrong to say there is no risk.
