Please branch and build antlr3 in epel10. If you do not wish to maintain antlr3 in epel10, or do not think you will be able to do this in a timely manner, the EPEL Packagers SIG would be happy to be a co-maintainer of the package; please add the epel-packagers-sig group through https://src.fedoraproject.org/rpms/antlr3/addgroup and grant it commit access, or collaborator access on epel* branches. I would also be happy to be a co-maintainer (FAS: salimma); please add me through https://src.fedoraproject.org/rpms/antlr3/adduser
Sorry for the delay. I have been mostly out of commission for the last couple of weeks and am now frantically trying to catch up on everything that piled up during that time. I have added you and epel-packagers-sig.
This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle. Changing version to 42.
