[jira] [Commented] (KARAF-1973) NullPointerException when
performing log:clear then log:tail

Freeman Fang commented on KARAF-1973:
-------------------------------------
Yeah, most likely KARAF-546 already fixed it, and the FUSE ESB version(7.0.2.fuse-097) you're using definitely already have this fix. I also tried that version and log:clear|log:tail just works for me and I can't reproduce this NPE. Could you elaborate how we can reproduce it?

[jira] [Commented] (KARAF-1973) NullPointerException when
performing log:clear then log:tail
Posted by "Heath Kesler (JIRA)" <ji...@apache.org>.

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.
