Process instance visualisation broken in 5.16.1 ?

[wsalembi]

We upgraded activiti from 5.13 to 5.16.1. The process instance visualisation seems broken in Manage > Administration > Running process instances. It still works for Completed process instances.

We encounter a NPE in the explorer UI. Details here: http://jira.codehaus.org/browse/ACT-2095

Any users encounter the same problem?

Is it related to this refactoring in 5.16? https://github.com/Activiti/Activiti/commit/1436f110489a5990a7080e4648f44dad2a499072
