The issue is not reproduced at master.

The issue is reproduced at 6.2.x branch following this steps:

1. Create a new site
2. Import two images at document library
3. Activate local staging
4. Create one page
5. At this page add two webcontent, at ckeditor, each webcontent must include a image from DL:
6. Publish to Live:
   1. At "Content" section, select "Choose Content" => "Date Range" => "From Last Publish Date Change"
   2. The publication process will work fine
7. Reorder webcontent portlets at page (And/Or) Add other non webcontent portlet, like blog portlet
8. Publish again to live:
   1. At "Content" section, select "Choose Content" => "Date Range" => "From Last Publish Date Change"
   2. The publication process will FAIL, showing the error "java.lang.NullPointerException"

IMPORTANT: At 6.2 SP5 version, the issue is also reproduced when you Publish to Live and at "Content" section, select "All Content", this problem is fixed with LPS-42218, but this is not included at SP5, so this other LPS must be also added to future fixpacks.

At log file, the folowing error will be shown:
