- java 8 support in gwt 2 answers
i have application developed using gwt 2.6 , java 7. updating java 8 gwt 2.6.
- is gwt 2.6 compatible java 8? build/compile fine?
- is gwt 2.7 compatible java 8? suggestion?
if you're interested in using jdk 8 compile application, without using java 8 language constructs, gwt 2.6 , 2.7 work.
java 8 source language won't supported before gwt 2.8 though, pointed others.
