Subject: Fix: Crash on lttng list -j/-l/-p when no events are present
X-Git-Tag: v2.7.0-rc2~180
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=7edc8ff0bbf8110f5333d108ecb83c1059849f10;p=lttng-tools.git

Fix: Crash on lttng list -j/-l/-p when no events are present

The lttng client will free an uninitialized pointer whenever a the
lttng list command is invoked on a domain which involves the log4j,
JUL or Python agents.
