[jira] [Updated] (MYFACES-4107) StringIndexOutOfBoundsException in
getResourceVersion
[ https://issues.apache.org/jira/browse/MYFACES-4107?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bill Lucy updated MYFACES-4107:
-------------------------------
Status: Patch Available (was: Open)
> StringIndexOutOfBoundsException in getResourceVersion
> -----------------------------------------------------
>
> Key: MYFACES-4107
> URL: https://issues.apache.org/jira/browse/MYFACES-4107
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.0.24, 2.1.18, 2.2.12
> Environment: WebSphere Liberty
> Reporter: Bill Lucy
> Assignee: Bill Lucy
> Priority: Minor
> Attachments: MYFACES-4107.patch
>
>
> I've run into a case where, given an incorrect context parameter, a StringIndexOutOfBoundsException is thrown. This occurs in WebSphere Liberty because the server normalizes the external context resource paths during app initialization.
> For example, this parameter:
> <context-param>
> <param-name>javax.faces.WEBAPP_RESOURCES_DIRECTORY</param-name>
> <param-value>/META-INF/resources</param-value>
> </context-param>
> throws:
> java.lang.StringIndexOutOfBoundsException: String index out of range: 35
> at java.lang.String.substring(String.java:1377)
> at org.apache.myfaces.shared.resource.ExternalContextResourceLoader.getResourceVersion(ExternalContextResourceLoader.java:81)
> That parameter value is not allowed to have a leading slash. However, the current exception is not very helpful, and can be easily avoided.
> I'll attach a patch which avoids the StringIndexOutOfBoundsException in getResourceVersion(); we already have this logic in getLibraryVersion().
