Thank you for answers.
I tried using @Deprecated (since="2.0", forRemoval=true) and got compilation errors, then i found out that the GWT default JRE emulation uses JDK8 java.lang.Deprecated which may or may not have been the culprit to my issues.
So i asked to get confirmation by the community.

Am i correct in thinking that GWT2.9.0 does not support the syntax of JDK9 or higher?No.You can use up to Java 11 syntax.2. Can i use Java11 with GWT2.9.0 to compile my application?Yes.Fwiw, the answers to these questions are in http://www.gwtproject.org/release-notes.html#Release_Notes_2_9_0, in the highlights:> Added support for Java language levels 9, 10, and 11.> […] The release was tested and found to work cross platform when run with Java 8, 11, and 14.
