----------------------------------
Summary: Reflections library 0.9.12 introduced in 2.5 causes
regression scanning for plugins on plugin_path
Key: KAFKA-9712
URL: https://issues.apache.org/jira/browse/KAFKA-9712
Project: Kafka
Issue Type: Bug
Affects Versions: 2.5.0
Reporter: Nigel Liang
Reflections v0.9.12 was introduced in 2.5 branch to remove Guava dependency -
https://issues.apache.org/jira/browse/KAFKA-3061
This version, however, contains a
[bug|https://github.com/ronmamo/reflections/issues/273] that will cause
regression when scanning for plugins if the `plugins_path` specified does not
contain valid plugins. The case where we were able to repro this, the
`plugins_path` was misconfigured to point to `~/.ssh` which contained unrelated
files but no plugins. Further testing is needed to figure out if it will repro
for other cases such as empty directory, combination of valid and invalid
plugins in directory, just some types of plugins and not others in directory,
etc.
