[jira] [Resolved] (WW-3910) NPE in DefaultStaticContentLoader
during startup
Posted by "Lukasz Lenart (JIRA)" <ji...@apache.org>.

Lukasz Lenart resolved WW-3910.
-------------------------------
Resolution: Fixed
Assignee: Lukasz Lenart
[~mhankus] you are right, returning nulls is wrong ;-)
I've turned String[] into List<String> - hope it will not break anything and returning empty List instead :-)

[jira] [Commented] (WW-3910) NPE in DefaultStaticContentLoader

Mirek Hankus commented on WW-3910:
----------------------------------
Providing test case make take a while, because project is complex.
Anyway, please note that
# method parse of DefaultStaticContentLoader may return null (javadoc does not say a word about returning null
# result of parse is set to {code}this.pathPrefixes = parse(packages);{code} without checking for null result
# rest of DefaultStaticContentLoader assumes that this.pathPrefixes is not null
so there needs code needs some fixes:
# javadoc should state that parse may return null, or parse should always return String[] (event empty one).
# code should check for null result (if parse is supposed to return null)
Root cause of this problem is unknown right now. I will investigate problem.
