Alternative JDKs for building and running - OpenJDK 6, 7, Sun JDK 7, IcedTea ---------------------------------------------------------------------------- Key: WFLY-598 URL: https://issues.jboss.org/browse/WFLY-598 Project: WildFly Issue Type: Sub-task Reporter: Ondrej Zizka Assignee: Ondrej Zizka Labels: eap6_prd_req James Perkins: {quote} At one point there was a JIRA for OpenJDK 6, in fact I think a couple. The issue with OpenJDK 6 is in the build we use some JavaScript and OpenJDK 6 doesn't come with a JavaScript engine. I tried a couple things to get Rhino working with it as that's what the Sun JDK uses, but I think it needs to implement an SPI to get it to work. I didn't look into it much beyond that. JDK 7 is a different issue. It's a bug in the annotation processing API which the JBoss Logging Tooling uses. I just refreshed my OpenJDK 7 update source and it looks like the bug is fixed in there. It's fixed in IcedTea as well. There could be the JavaScript issue here as well I can't actually remember, but I thought I had some successful builds with custom JDK's I compiled. I did just try with IcedTea 7 and got some other errors. I'm building the latest upstream of OpenJDK 7 now and we'll see if it works. I'll let you know either way. Let me know if you have any more questions on this. I did dig into a while ago a little. {quote}
