• Key: AMQ-752
• Type: Bug
• Status: Resolved
• Resolution: Fixed
• Priority: Blocker
• Assignee: Unassigned
• Reporter: James Strachan
• Fix Version/s: 4.0.1, 4.1.0

Description

all the various LICENSEs need to be appended into a single LICENSE and the notices consolidated.

Also we might want to...

• the MANIFEST lacks a Implementation-Vendor-Id. not reported harmful but is
  in the spec. suggested value: org.apache.

• the MANIFEST lacks a Specification-Version but has an
  Implementation-Version. suggested value 4.0.

• better if the source extracts into a directory with a different name from
  the binary distribution. for example, incubator-activemq-src for the source
  and incubator-activemq for the binary (say.

• i would prefer the binaries and distributions names to contain apache. for
  example apache-incubator-activemq.
