PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server 6.0.2.x users
migrating from WebSphere InterChange Server

PROBLEM DESCRIPTION:
Customer can't execute after migration

RECOMMENDATION:
None

Potential infinite loops generated in migrated BPEL.  When we
"unravel" a loop in the ICS CWT, the case where there is
an EndSuccess within the loop is not correctly handled. As a
result, a While loop is generated in the BPEL that can
result in an infinite loop which causes the timeout issue.

PROBLEM CONCLUSION:                                             
This problem was fixed in the first private, but it introduced  
the "parallel link-to-link" issue. This issue is fixed by       
changing the equals() method on the Link.java class so that     
links with the same source and target are considered "equal"    
if their conditions are both null.
