Bug ID: 56441
Summary: Misleading error message in FilterBase cause by
invalid regex
Product: Tomcat 7
Version: 7.0.29
Hardware: All
OS: Linux
Status: NEW
Severity: minor
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: matty_rid...@hotmail.com
An invalid regex in the allow parameter leads to raising of a misleading
exception: The property "allow" is not defined for filters of type
"org.apache.catalina.filters.RemoteAddrFilter".
Test config in web.xml
<filter>
<filter-name>TestFilter</filter-name>
<filter-class>org.apache.catalina.filters.RemoteAddrFilter</filter-class>
<init-param>
<param-name>allow</param-name>
<param-value>127\.0\.\0.1</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>TestFilter</filter-name>
<url-pattern>*</url-pattern>
</filter-mapping>
