From this other SO Q&A it is evident that JBoss EAP 6.1.0 is based on JBoss AS 7.2.0! From the JBoss Github account it appears that JBoss AS 7.2.0 was the final community release (available in source-form under LGPL). However, I do not find any JBoss AS 7.3.0 or newer release on which the newer versions of JBoss EAP s.a. 6.2.0 and 6.3.0 are based. I do find however that JBoss AS 8 is now renamed as Wildfly, but not at all clear, if that happens to be the basis of say JBoss EAP 6.3.0.
Can anyone clarify ? Is it that RedHat/JBoss have ceased to release software which could be used to build equivalent binary, even if run without support ? While I won't be surprised, because that makes perfect commercial sense, but just wanted to be sure that I am not missing anything here.
The EAP code repository was forked/rebased from AS7 after 7.2.0 tag.
And as such has its own lifecycle and has diverted considerably from AS7/WildFly (upstream) repository.
In short there is no such thing as JBoss 7.3 or 7.4 as it is internal version.
Code for all EAP releases is available on ftp and you can always build it yourself and use without restrictions (ftp://ftp.redhat.com/redhat/jbeap/).
You can see component details in https://access.redhat.com/articles/112673
In short, there is no a community version that corresponds to EAP 6.2 or 6.3 where you can download the binaries
