>    Affects Versions: 4.1.0
>         Environment: n/a

> I can't find a file detailing which exact version of activeMQ I've uncompressed.
> The actual 4.1 tarball currently have a filename "apache-activemq-4.1-incubator-SNAPSHOT",
not including anything more specific.
> Inside the tarball there's nothing detailing what exact version we're at. The same goes
for the jar-files themselves.
> *NOTE:* All this "as far as I can see" - I might have missed the obvious spot. If so,
> Inside the "full jar", the META-INF/MANIFEST.MF just states:
> {code}
> Manifest-Version: 1.0
> Archiver-Version: Plexus Archiver
> Created-By: Apache Maven
> Built-By: chirino
> Build-Jdk: 1.5.0_06
> {code}
> The information in these files are the information that will show up in the java.lang.Package
object for the Classes that was loaded from the jar in question, and its methods getSpecification[Title|Vendor|Version]()
and getImplementation[Title|Vendor|Version]() - which is nothing for activemq due to this
info completely missing.
> In comparison, here's a bunch of better manifests:
> Log4j: "log4j-1.2.12.jar" (note the version in the jar-name too, which is perfect) (This
MANIFEST file have missing date and Spec-triplet):
> Manifest-Version: 1.0
> {code}
> Ant-Version: Apache Ant 1.6.4
> Created-By: 1.3.1_16-b06 (Sun Microsystems Inc.)
> Name: org/apache/log4j/
> Implementation-Title: log4j
> Implementation-Version: 1.2.12
> Implementation-Vendor: "Apache Software Foundation"
> {code}
> And here's the spring jar actually included with the activemq distro (2.0), which is
called "spring-2.0.jar" (has missing date, spec-triplet):
> Manifest-Version: 1.0
> {code}
> Ant-Version: Apache Ant 1.6.5
> Created-By: 1.5.0_08-b03 (Sun Microsystems Inc.)
> Implementation-Title: Spring Framework
> Implementation-Version: 2.0
> Spring-Version: 2.0
> Premain-Class: org.springframework.instrument.InstrumentationSavingAgent
> {code}
> Here's a version of JGoodies Looks, which has the best MANIFEST.MF file of the lot (it
defines both Spec and Impl, perfect). The file's name is "looks-2.0-beta.jar". (The last piece
of information that would have been *nice* is explicit build-date, but presumably the date
mentioned in "Implementation-Version" is it (this is also definately the _correct_ thing to
> {code}
> Manifest-Version: 1.0

> Created-By: 1.5.0_06-b05 (Sun Microsystems Inc.)

> Specification-Title: JGoodies Looks API Specification

> *In addition*, it would be good if one of the txt-files of the root in the tarball included
all this information, and more. Everything about the build and its environment is nice to
have, including but not limited to all versions, checkout date, build date, full environment,
user, OS, OS-version, JVM-version - the lot.
