Guava 32.1.1 is not compatible with GWT because of System.nanoTime calls

[Arpic]

After updating to Guava 32.1.1 we cannot compile our GWT project anymore because of changes to the @GwtCompatible Ticker class:

[ERROR] Errors in 'com/google/common/base/Ticker.java'
    [ERROR] Line 53: The method nanoTime() is undefined for the type System
Tracing compile failure path for type 'com.google.common.base.Ticker'
    [ERROR] Errors in 'com/google/common/base/Ticker.java'
        [ERROR] Line 53: The method nanoTime() is undefined for the type System

Is it an issue in our setup or an incompatible change ?

Ah, support for nanoTime() is new in GWT 2.10.0. I should have thought to investigate that. I'll mention it in the release notes.

Is upgrading to 2.10.0 practical?

Ah yes, I didn't think to check the GWT release notes, I will investigate whether it's possible for us to upgrade. Thanks for the quick answer.
