Heath Kesler commented on KARAF-1973:
-------------------------------------
this issue appears to be fixed, I tested in 2.2.10-SNAPSHOT, 2.3, and 3.0 and
all worked as expected (no exceptions).
Steps to test:
- start karaf
- log:clear
- log:tail
- log:tail (again just to make sure it did not throw an exception the first
time)
no error
I also tried several combinations of clear and tail in between other commands,
just to make sure.
> NullPointerException when performing log:clear then log:tail
