I wanted to migrate from JBOSS EAP to a Wildfly version which supports older versions of Java like 6 or 5.

I can't find a compatibility matrix with wild fly and java.

What about wildfly 8 ? does it supports java older versions.

can someone point me to the matrix where I can find wildfly compatibility with Java

Thanks

  • As far as I know Wildfly 8 only supports Java 8+ while JBoss 7 only runs on Java up to 7 due to some "hooking" into JVM internals. So if you want to upgrade to Wildfly you'd also have to upgrade to a newer Java version. That normally should be easier than the Wildfly upgrade but it depends on what your code is doing - if it is tied to a certain Java version you might want to fix that anyway. – Thomas Aug 24 '20 at 07:35
  • @Thomas so according to you, What is the latest JBoss version which supports for java 6 or older versions ? –  Aug 24 '20 at 07:42
  • I can't tell for EAP since we've always used community editions but if I remember correctly it should be JBoss 6 or 7. However, for security reasons among others you'd normally want to upgrade to a newer Java version which in most cases should be a smooth operation at least if you upgrade to 8 (of course there might still be hiccups such as `compare()` methods being reported as not adhering to the contract or internal classes having been removed - but that's actually a good thing in most cases). – Thomas Aug 24 '20 at 07:54
  • WildFly only works with Java 8. JBoss EAP 7 also requires Java 8. Only JBoss EAP 6 or JBoss AS 7.1.1.Final would work with Java 6. – James R. Perkins Aug 25 '20 at 17:18
  • @JamesR.Perkins I think Wildfly 8 supports java 7. Could you please share any link where compatibility matrix mentioned. –  Aug 26 '20 at 03:54
  • It could be Java 7, however Java 7 is no longer supported and WildFly 8 is quite old now. I'm not aware of a compatibility matrix. – James R. Perkins Aug 26 '20 at 14:17

This is the closest thing to a compatibility matrix I can find. Which has a separate chart for both Wildfly and JBoss EAP: Choosing the right JDK for WildFly and JBoss EAP 7

It's obviously not official, but something is better than nothing.
