[jira] Commented: (DBCP-68) [dbcp] Commons Collection dependency version clash when using Commons DBCP via Maven2

    [ http://issues.apache.org/jira/browse/DBCP-68?page=comments#action_12435269 ] 
            
Phil Steitz commented on DBCP-68:
---------------------------------

Updating to collections 3.1 may cause dependency problems for some users.  Per discussion on commons-dev, I would prefer to bundle the required classes in their 2.1 versions.  There are two classes required - o.a.c.collections.LRUMap and o.a.c.collections.SequencedHashMap and only one dbcp class that depends on them - o.a.c.dbcp.datasources.SharedPoolDataSource.   The collections classes have been deprecated, but still exist, in Collections 3.x.  I propose that we take the versions from the collections 2.1 source and include them with package scope in o.a.c.dbcp.datasources, then remove collections dependency altogether.

>         Environment: Operating System: All

> When using Maven2 to incorporate Commons DBCP 1.2.1 into your project a
> transient dependency on Commons Collections 2.1 is added. This will clash with
> other Commons Components like Commons Configuration 1.2 for example that depend
> on Commons Collections 3.1. Upon adding Commons DBCP 1.2.1 to your project the
> existing transient dependency on Commons Collections 3.1 gets changed into
> Commons Collections 2.1. This will result in runtime errors like the following:
> java.lang.NoClassDefFoundError: org/apache/commons/collections/map/LinkedMap
> 	at
> org.apache.commons.configuration.BaseConfiguration.<init>(BaseConfiguration.java:53)
> Since Commons Collections is incorporated into most Commons Components please
> update the dependency within Commons DBCP to Commons Collections 3.1 if possible.
