log goes invisiable after creating an issue via groovy script

[liansheng zhang]

Following codes is to create an issue.

before calling issueService.create(), I add a log "before". 
after calling issueService.create(), I add a log "after"

when I go to see the log, only "before" is printed, no "after"
no exception log either.
 

Weird. it is because issue is creatd in a service? How to show the log.



IssueService issueService = ComponentAccessor.getIssueService();
IssueInputParameters issueInputParameters = issueService.newIssueInputParameters();
issueInputParameters.setProjectId(newProjectObj.getId())
    .setIssueTypeId(newIssueTypeId)
    .setSummary(issue.getSummary())
    .setAssigneeId(assignee)
    .setDescription(desc)
 //   .setComment(desc)
    .addCustomFieldValue(epicNameFieldId, issue.getSummary())

IssueService.CreateValidationResult createValidationResult = issueService.validateCreate(curentLoggedInUser, issueInputParameters);

if(!createValidationResult.isValid()){
    for(String registeredErrorMessage:createValidationResult.getErrorCollection().getErrors().values())
    {
        log.warn("validation result: " + registeredErrorMessage);
    }
}
else {
    try {

        log.warn("before")
        IssueService.IssueResult createResult = issueService.create(curentLoggedInUser, createValidationResult);
        log.warn("after")

        if (!createResult.isValid())
        {
            log.warn("!createResult.isValid()  is true")
            // Do something
        }
    }catch(Exception e){
        log.("we met exception when creating issue. " + e.getMessage())
    }

}
