在使用Activiti 5.8版本时遇到生成流程图异常，错误信息为`java.awt.image.RasterFormatException: (x + width) is outside raster`。解决方法是将`RepositoryService`转换为`RepositoryServiceImpl`，并通过`getDeployedProcessDefinition`方法获取流程定义，从而避免异常。

Activiti生成流程图代码：

ProcessDefinitionEntity p = (ProcessDefinitionEntity)repositoryService
				.createProcessDefinitionQuery()
				.processDefinitionId("test:2:13708")
				.singleResult();
InputStream in =  ProcessDiagramGenerator.generateDiagram(p,"png", Arrays.asList("usertask1"));

抛出异常：

java.awt.image.RasterFormatException: (x + width) is outside raster
