Bug ID: 57129
Summary: Regression. Load WEB-INF/lib jarfiles in alphabetical
order
Product: Tomcat 8
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: j...@jorgenpersson.se
When the classpath are created for the webapp classloader, the ordering of the
jar files are not the same in Tomcat7 vs Tomcat8.
This is due to that in Tomcat7, the FileDirContext.list(File) method sorts the
jar files in the WEB-ING/lib folder alpabetically:
...
Arrays.sort(names); // Sort alphabetically
NamingEntry entry = null;
for (int i = 0; i < names.length; i++) {
...
The new design in Tomcat8 does not do this. I've identified two places where
WEB-INF/lib is read:
StandardRoot.list(String, boolean)
and
DirResourceSet.listWebAppPaths(String)
Even though it is not a requirement that the entries are ordered
alphabetically, it would be nice if they were. And there is no harm in doing it
for web applications that does not depend on classpath ordering.
I've attached a patch file, tomcat8.patch, based on tomcat8 trunk (@ rev.
1633538).
