JasperReports-6.7.0 Version does not match with reported version from the jar file in

I confirmed the following:

META-INF/MANIFEST.MF say 6.6.0
META-INF/maven/net.sf.jasperreports/jasperreports/pom.* say 6.7.0

So I initially suspected this to be a packing issue at source. But I just noticed the pom.xml says:

<scm>
<connection>scm:git:https://github.com/TIBCOSoftware/jasperreports.git</connection>
<tag>jr-6-6-0</tag>
<url>https://github.com/TIBCOSoftware/jasperreports</url>
</scm>

I filed a bug 11286 to track this upstream.

Upstream has confirmed this is a packaging-ony issue, previously reported and discussed on the github tracker here. It is clear that the JARs are 6.7.0 content with incorrect metadata, so I believe this issue can be resolved.
