------------------------------------

             Summary: Support Guava version 21.0
                 Key: CALCITE-1590
                 URL: https://issues.apache.org/jira/browse/CALCITE-1590
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


Guava version 21.0 is an important version because it is the first with JDK 8 support (hence lambdas). Make sure that Calcite runs on it (on JDK 8 and later). Continue to support other versions of Guava as early as 14.0.1.

Compilation using {{mvn clean -Dguava.version=21.0 clean test}} on JDK8 currently yields many errors like the following:

{noformat}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project calcite-core: Compilation failure: Compilation failure:
