[ https://issues.jboss.org/browse/WFWIP-21?page=com.atlassian.jira.plugin.s... ] Martyn Taylor edited comment on WFWIP-21 at 8/22/18 7:03 AM: ------------------------------------------------------------- I think this one is caused by WFWIP-56. The NPE [~jbertram] reported is due to an empty message body, which returns null on getObject(). There's an issue with the JDBC store (WFWIP-56) where calling open file (For large message in this case) auto creates the file in the DB table. But it appears it;s not thread safe which can result in 2 files being created with the same name, only one has the data. Upon read, the other file is used and so the message body is empty. I believe this issue is already present in 1.5.x so shouldn't be a blocker for the upgrade. [~eduda] can you kick off a run to confirm.
