Drop JDT for JSR-199 in jastow

[pmm]

I wanted to post this in "WildFly Development" but can't post there.

I wanted to ask whether there are any plans to replace the Eclipse JDT compiler in jastow (JSP implementation) with JSR-199 (Java Compiler API)? The advantage would be that we could save about 1.5 MB from the final archive size. The downside would be that JSPs would require a JDK and would no longer work on a JRE. Currently the JSP refernce implementation uses JSR-199.

We don't really have the resources to do this, and it would likely result in some compatibility problems. It also might result in different behaviour on different JDK's, which would be a problem.

Well it would be one class that's about 500 LoC that can be taken either from the RI or the java.net project. Nothing compared to let's say writing a full servlet implementaiton from scratch.

Well that's what we have TCKs for. Given that WildFly depends on on sun.misc.Unsafe and sun.reflect.ReflectionFactory I have a hard time understanding this argument.
