getNamespaceVersion() returns NULL for Renjin extensions (packages)

[perNyfelt]

This works:

print(getNamespaceVersion("base"))

version
"3.5.3"

However getNamespaceVersion on Renjin extensions returns NULL e.g.

> library("assertthat")
Loaded org.renjin.cran.assertthat version 0.2.1-b10.
> print(getNamespaceVersion("assertthat"))
NULL

I have tried with several of my own packages as well with the same (NULL) result (both when specifying the groupId and not, e.g.

> library("se.alipsa:xmlr")
Loaded se.alipsa.xmlr version 0.2.1.
> print(getNamespaceVersion("xmlr"))
NULL
> print(getNamespaceVersion("se.alipsa:xmlr"))
NULL

The same code in GNU R (3.6.3) results in:

> library("xmlr")
> print(getNamespaceVersion("xmlr"))
version 
"0.1.0" 

Result is the same on Renjin Console and when running from the Scripting Engine.

Tested on Renjin versions 3.5-beta76 and master branch as of 2022-Jan-12.

On a similar note:

print(installed.packages(fields = c ("Package", "Version")))

Does not list any Renjin Extensions, only base stuff such as stats, stats4, graphics etc.

This is probably related to issue #483
