Hello, C3 developers.
After C3 has updated its dependencies to use AspectJ 1.6.11 it become
impossible to use it with Jetty 7.
The problem could be easily reproduced in cocoon-sample-webapp by
replacing maven-jetty-plugin of Jetty 6 with the following (actually any
Jetty 7 version will give the same result):
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>7.4.5.v20110725</version>
<configuration>
<connectors>
<connector
implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
<port>8890</port>
<maxIdleTime>30000</maxIdleTime>
</connector>
</connectors>
<webAppSourceDirectory>${project.build.directory}/${project.artifactId}-${project.version}</webAppSourceDirectory>
<contextPath>/</contextPath>
</configuration>
</plugin>
I've tried to debug this problem and it seems that it is related to two
things.
1) AspectJ in version 1.6.7 changed the way how it does static
optimizations, so some cases that were working before are broken because
it has not enough information at the optimization time.
2) Cocoon Servlet Service Framework is the one of such cases. It fails
on
cocoon-servlet-service-impl-1.2.0/META-INF/cocoon/spring/cocoon-ssf-urlhandler-advice.xml
where it tries to apply pointcut "execution(*
javax.servlet.Servlet.service(..)) and bean(*/embedded)" to the
ServletContext. The problem is that Jetty 7 returns an implementation
instance that is isolated from the web-app classloader. It is perfectly
legal and I believe same thing will happen on most modern JEE
containers, especially when many of them are moving to OSGI and
alternatives. AspectJ tries to resolve this hidden class by name and
fails, so it cannot validate if it can do optimizations and then fails
with the described error.
I think it serious problem and need to be solved... As I can see SSF has
not been changed for long time, so do we have anyone who remembers how
it works and is able to fix it? Where to submit bugreport? SSF is
technically in Cocoon 2 JIRA, while almost no activity happening there
and I am not sure it will be noticed there, while Cocoon 3 does not have
SSF component...
