--------------------------------------------------------------
To illustrate the problem, I attached a simple dummy test. After deploying  it (execute the deploy class) and istantiating (using the class CreateInstance) a process with a test variable (testvar) that should be stored in a long text field  is created. the acutal code looks as follows:


ProcessEngine processEngine = new Configuration().setResource("jbpm.cfg.xml").buildProcessEngine();

 RepositoryService repositoryService = processEngine.getRepositoryService();
 ExecutionService executionService = processEngine.getExecutionService();

 Map<String, Object> variables = new HashMap<String, Object>();
 variables.put("testvar", "This is a test variable for a text".toCharArray());        
 executionService.startProcessInstanceByKey("test", variables);    

After  creating the instance with the long text variable testvar, the following exception occurs:

I didn't find an open issue in the ticket tracker. Are there any ideas?
