I have got closer to why it is happening. I wrote a small dtrace[1]
script to monitor open system calls for those additional class files. I
attached it to a build m/c and after around 150 builds, once it
occurred. Every time open system call was made with that file handle, I
print the java stack. The output of dtrace is attached here with. That
file got opened three times. As the stack suggests, first by
maven-compiler-plugin, then by maven-bundle-plugin and finally by
maven-jar-plugin. So, it is the compiler-plugin that is responsible for
creating that servlet class in jacc target dir. That is very surprising.
*Why would compiler-plugin compile dependencies? *Any clue?
Thanks,

We are experiencing an issue in our build system and it is not
happening for every one. I used to think it only happens for mvn
2.0.8, but just now a developer told me that they see it mvn 2.0.7 as
well. For whatever reason, sometimes, a jar artifact is containing not
only the classes compiled from the sources that are part of that
artifact, it also contains dependent .class files. It is a very
serious problem for us. Given below is the artifact that's causing
trouble.
<project ...>
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.glassfish</groupId>
<artifactId>api-pom</artifactId>
<version>10.0-SNAPSHOT</version>
</parent>
<artifactId>javax.security.jacc</artifactId>
<packaging>jar</packaging>
<name>javax.security.jacc API v.1.2</name>
<dependencies>
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.servlet</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
</project>
As you can see, it depends on
org.glassfish:javax.servlet:10.0-SNAPSHOT, which is a jar type
artifact and contains javax.servlet classes. I can assure you that in
the source tree of javax.security.jacc module, there is no
javax.servlet class. Yet, javax.security.jacc-10.0-SNAPSHOT.jar
contains a bunch of javax.servlet classes. I should also state that it
only happens when both javax.servlet module and javax.security.jacc
module are part of same maven reactor. The build log produced with -X
option is quite large, so I am supplying log for jacc module portion
only. Pl. see the attachment called build.all.jacc.log. I will be
happy to supply more of it if need be. I should say, I don't
understand something from the log file. I am highlighting it here with
bold letters:

What does this active project artifact mean? By looking at the
attached log file, do you have any suggestion for me?
Thanks,
