It seems i'm unable to find any information on SNSP-ARJP-EUR-2, everything I see is the SNSP-ARJP-EUR-1 for THQ.
If it's confirmed by some sources for the JVC release to have been released on March 30, 1995, that information can be supplied and will be approved if it's resubmitted
It might not be perfect proof but I still want to show what I found
I just researched for a bit and ended up looking through old magazines linked in the sources of the Wikipedia page for the game. (
https://en.wikipedia.org/wiki/Super_Star_Wars:_Return_of_the_Jedi )
JVC
- Source 12 is a PDF which has a review of Return of the Jedi on page 122-123 (Or 150-151 in the PDF) which only mentions JVC as the publisher.
- The back side of the manual of the JVC version also states it's exclusively published and distributed by JVC ( A readable picture of the manual is in this offer

THQ
- Source 6 of Wikipedia is also a PDF which states that Super Return of the Jedi will be rereleased by THQ alongside the special editions of the movies in 1997 (Just a short sentence in brackets on the bottom of page 22).
- The manual of THQ also does not mention any exclusivity ( A readable picture of the manual is in this offer
https://www.ebay.de/itm/364631466342 ).
This would align with the info from gamefaqs.
Most other sources I saw state that the original release was by JVC and THQ only did a rerelease but those were mostly only some forum entries or sites were I don't know if the info is user distributed - such as snes central.
EDIT: Added the Wikipedia page for better traceability
