The JBoss spec fork of the EL API is based on the 3.0.3 release of https://github.com/eclipse-ee4j/el-ri but our impl module is using the 3.0.2 release. So we should upgrade to align the API and impl, plus to use the latest.

The code difference between 3.0.2 and 3.0.3 is huge but it appears to be "jakarta-ization" kinds of things – whitespace, code style etc.
