Subject [jira] Commented: (HTTPCLIENT-866) HttpClient depends on jcip-annotations.jar
Date Fri, 21 Aug 2009 13:52:14 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745971#action_12745971
] 

Sebb commented on HTTPCLIENT-866:
---------------------------------

Suppose Client 4.0.1 is created with the classes, Core 4.0 has not got them.

We then create Client 4.0.2 without the classes, and Core 4.0.1 with the classes.

What happens if an exisiting Client 4.0.1 + Core 4.0 is upgraded to Client 4.0.1 + Core 4.0.1?

Won't it cause a problem to have two copies of the classes?

Or maybe we can just document that certain combinations of versions are incompatible?

> When using Java 5 to compile code that uses HttpClient, jcip-annotations.jar must be
in the classpath or else you get a compiler error:
>     [javac] /path/to/src/SomeFile.java:129: cannot access net.jcip.annotations.GuardedBy
>     [javac] file net/jcip/annotations/GuardedBy.class not found
>     [javac]         DefaultHttpClient httpclient = new DefaultHttpClient();
>     [javac]                                        ^
> With Java 6, you get a bunch of warnings instead.
>     [javac] org/apache/http/impl/client/AbstractHttpClient.class(org/apache/http/impl/client:AbstractHttpClient.class):
warning: Cannot find annotation method 'value()' in type 'net.jcip.annotations.GuardedBy':
class file for net.jcip.annotations.GuardedBy not found
> This requirement doesn't seem to be documented anywhere, and jcip-annotations.jar is
not included in the "httpcomponents-client-4.0-bin-with-dependencies" package.
