---------------------------------------

Hi,

This command don't work, I don't know if it's related to this issue :

{code:java}
karaf@root()> history | grep cave
grep: java.lang.ArrayIndexOutOfBoundsException: 29
{code}

But this command work's :

{code:java}
karaf@root()> history | exec grep cave
  1149  feature:repo add cave
  1150  feature:repo-add cave
  1151  feature:install cave-server
  1152  feature:install cave-storage
{code}

*grep* work's only with *exec* after *history* 

However, *grep* work's without exec with *feature:list*

{code:java}
karaf@root()> feature:list | grep -i cave                                                                                                                                                                                                     
cave-server                     │ 4.0.1.SNAPSHOT   │ x        │ Started     │ karaf-cave-4.0.1-SNAPSHOT         │
cave-storage                    │ 4.0.1.SNAPSHOT   │          │ Started     │ karaf-cave-4.0.1-SNAPSHOT         │
{code}

Tested on SNAPSHOT from Jenkins : apache-karaf-4.2.0-20171012.141014-387

> The following command behaves correctly:
> {code}
> echo foo | grep o
> {code}
> However, the following one never ends:
> {code}
> echo foo | exec grep o
> {code}
> The following ones also behaves incorrectly (enter does not print a new line, and Ctrl+C / Ctrl+D are not handled correctly) :
> {code}
> grep o
> {code}
