Felix Meschberger created SLING-6226:
----------------------------------------
Summary: substVars not properly handling unknown properties
Key: SLING-6226
URL: https://issues.apache.org/jira/browse/SLING-6226
Project: Sling
Issue Type: Bug
Affects Versions: Launchpad Base 2.6.14
Reporter: Felix Meschberger
Fix For: Launchpad Base 2.6.16
Assuming a property in {{sling.properties}} of the form
{code}
org.apache.sling.commons.log.pattern=%d{yyyy-MM-dd HH:mm:ss.SSSXXX} *%level*
[%thread] %logger %msg%n
{code}
This will break during Sling startup as the date format of this {{log.pattern}}
ends with a curly brace but is not matched with a {{ $\{ }}. This is a but in
the {{substVars}} method.
Another problem is that this method is duplicate in the {{Sling}} and
{{SlingServlet}} classes where the latter is in the web app class loader while
the former already is in the launcher class loader.
Proposing a patch taking the latest Felix Framework's Util class creating a new
{{Util}} class in the shared package.
