This refers to https://java.net/jira/browse/GLASSFISH-17606 which was fixed here, https://java.net/projects/uel/sources/svn/revision/340 and was eventually backported to WildFly and JBoss EL 3.0 as part of JBEE-133 "Updates to v3.0 of EL API Specification" here: https://github.com/jboss/jboss-el-api_spec/commit/7178718f6cccdae451caa86ead0d146cfef9cf7d.
Can this be backport to EAP 6 by any chance? Of course this would probably make into EAP 6.4 CP01.
SET/GSS - please provide test (as discussed on triage) to increase CP throughput.
I will qa_ack afterwards or when the scope of CP01 is clear and we have enough seats.
qa_acking per Comment 5
Yes upgrade should be reverted to 1.0.4.Final-redhat-1 as that was the version used in 6.3 and 6.4 and it was confirmed to work.
jboss-el-api_spec was reverted to 1.0.4.Final-redhat-1 in CR3
