catalina.base using docBase causes
NullPointerException
Product: Tomcat 8
Version: 8.5.12
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Manager
Assignee: dev@tomcat.apache.org
Reporter: jamie.hank...@gmail.com
Target Milestone: ----
Repro:
1. Set CATALINA_HOME to "C:\Program Files\Apache Software
Foundation\apache-tomcat-8.5.12"
2. Set CATALINA_BASE to "C:\ProgramData\Tomcat"
3. Add file "C:\ProgramData\Tomcat\conf\Catalina\localhost\host-manager.xml"
with following content:
<Context privileged="true" antiResourceLocking="false"
docBase="${catalina.home}/webapps/host-manager">
</Context>
4. Start Tomcat and navigate to http://localhost:8080/host-manager
Tomcat hits the following exception:

Here's the offending line, mappingData.pathInfo is null:
>mapping = new MappingImpl(mappingData.pathInfo.toString().substring(1),
> mappingData.wrapperPath.toString() + "/*",
> mappingData.matchType, servletName);
