I am running Update 3 for EAP 6.3 and when I put a lambda expression (java 1.8 feature) in a CDI bean the deployment fails with:

JBAS015852: Could not index class org/jboss/as/quickstarts/helloworld/HelloService.class at /c:/install/jboss-eap-6.3.3/bin/content/jboss-helloworld.war/WEB-INF/classes: java.lang.IllegalStateException: Unknown tag! pos=5 poolCount = 80

at org.jboss.jandex.Indexer.processConstantPool(Indexer.java:606) [jandex-1.0.3.Final-redhat-2.jar:1.0.3.Final-redhat-2]

...

Seems to me that lambdas can not be user in conjunction with CDI in Update 3 for EAP 6.3. Is that a correct statement or something is wrong at my end?

That does sound similar to these issues: [WFLY-2287] Java 8 Class files not loading in Beta1 - JBoss Issue Tracker and [JANDEX-14] Jandex doesn't work with invokedynamic constant pool tag - JBoss Issue Tracker.

Yes fix is updating jandex, preferably to 1.2.x.Final version.

if you want to do it manually download  https://repository.jboss.org/nexus/service/local/repositories/central/content/org/jboss/jandex/1.2.3.Final/jandex-1.2.3.…

and put it into JBOSS_HOME\modules\system\layers\base\org\jboss\jandex\main and then update reference to the new file in module.xml

EAP 6.4.x builds already have this fixed. With patch for 6.3 coming.

Thanks Tomaz. That solved the issue.

makes no mention of JDK 1.8 as being a supported platform for 6.3. I'm still waiting on our OPs team to provide installer to verify. Can someone from RedHat clarify this please?

FYI..

In case anyone is interested I found this link on customer portal with official answer:

Support for Java 8 in EAP - Red Hat Customer Portal

"Starting with 6.3 update 3 (6.3.3) and continuing with 6.4, Oracle Java SE 8 is both a supported and tested configuration."
