Webapp root null

[jendib]

It seems that FilterConfig.getSerlvetContext().getRealPath("/") returns null in some cases, so theme directory search fails in DirectoryUtil.getThemeDirectory()

Maybe http://stackoverflow.com/a/536260 is an answer?

Reproduced with the following settings:

• Tomcat 8
• In server.xml: unpackWARs="false"

The theme resource returns a NPE.

The reader.home property is not used if unpackWARs="false", check DirectoryUtil:41
if (EnvironmentUtil.getWebappRoot() != null)
