SYMPTOM
Users may face an issue with ESRI maps when using custom shapes in 10.11. The error message will mention the following line in details section of the error message:
com.Strategy.web.tasks.TaskException: java.lang.NullPointerException

CAUSE
The issue might be caused by shape definition for the custom shapes. It has been found that some specific shape IDs cause null pointer exceptions like the one mentioned above. Recommendation is to use higher numbers, like 1000 and over.
ACTION
Avoid setting the shape IDs to values like:
7, 101, 102, 103, 104
There possibly are more IDs that cause the troublesome behavior.
WORKAROUND

• access location of the file describing the shapes and layers and open it with Notepad++
• edit the shape ID of suspected shape to a different number, e.g. 11: 

• save the file
• restart the Web server
• re-test
