Problem with Reverse Replication

Avatar

Level 9

Hi All,

We have customised OOTB reverse replication workflow by adding an extra process.This process actually pauses the actual reverse replication operation to be begun.But an exception is being thrown when creating a work item of this process.

Code of Custom Process:

<%@page session="false" %>
<%
java.lang.Thread.sleep(1000);
%>

Exception:

com.adobe.granite.workflow.WorkflowException: Script execution resulted in an error at com.adobe.granite.workflow.core.job.HandlerBase.executeProcess(HandlerBase.java:176) at com.adobe.granite.workflow.core.job.JobHandler.process(JobHandler.java:244) at org.apache.sling.event.impl.jobs.JobConsumerManager$JobConsumerWrapper.process(JobConsumerManager.java:500) at org.apache.sling.event.impl.jobs.queues.JobQueueImpl.startJob(JobQueueImpl.java:291) at org.apache.sling.event.impl.jobs.queues.JobQueueImpl.access$100(JobQueueImpl.java:58) at org.apache.sling.event.impl.jobs.queues.JobQueueImpl$1.run(JobQueueImpl.java:227) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.sling.api.scripting.ScriptEvaluationException: java.lang.NullPointerException at org.apache.sling.scripting.core.impl.DefaultSlingScript.call(DefaultSlingScript.java:416) at org.apache.sling.scripting.core.impl.DefaultSlingScript.eval(DefaultSlingScript.java:184) at com.adobe.granite.workflow.core.job.HandlerBase.executeProcess(HandlerBase.java:174) ... 8 more Caused by: org.apache.sling.scripting.jsp.jasper.servlet.JspServletWrapper$1: java.lang.NullPointerException at org.apache.sling.scripting.jsp.jasper.servlet.JspServletWrapper.handleJspExceptionInternal(JspServletWrapper.java:655) at org.apache.sling.scripting.jsp.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:608) at org.apache.sling.scripting.jsp.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:533) at org.apache.sling.scripting.jsp.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:449) at org.apache.sling.scripting.jsp.JspScriptEngineFactory.callJsp(JspScriptEngineFactory.java:284) at org.apache.sling.scripting.jsp.JspScriptEngineFactory.access$100(JspScriptEngineFactory.java:102) at org.apache.sling.scripting.jsp.JspScriptEngineFactory$JspScriptEngine.eval(JspScriptEngineFactory.java:536) at org.apache.sling.scripting.core.impl.DefaultSlingScript.call(DefaultSlingScript.java:388) ... 10 more Caused by: java.lang.NullPointerException
