We're trying to use JBPM 3 with EJB 3, using the entityManager delegate to the JBPM Context.
We're having some problem during the removal phase of a stateful EJB, where apparently a Token's hashcode method get called, causing a NPE since it seems that the process instance is missing.
The NPE itself seems to occur here:
Caused by: java.lang.NullPointerException at org.jbpm.graph.exe.Token.hashCode(Token.java:611) at java.util.HashMap.putForCreate(HashMap.java:413) at java.util.HashMap.readObject(HashMap.java:1031) ... 199 more
Here's the full stack trace:
