Nullpointer when calling a subprocess with param and logging

[stroobat]

Following 3 criteria must be met:

1. Call a subprocess
2. With a parameter
3. With full logging

java.lang.NullPointerException

I use the Spring integration.
Whe you lower the logging, you will not get the exception.

I have created a Jira issue that contains all the info with testcase and potential fix !

Ok,

This gave me a good opportunity to look at the code though … 

Thanks.
