Julian Hyde commented on CALCITE-6588:
--------------------------------------

When this case is fixed, re-enable CalciteRemoteDriverTest by removing the 
{{assertThat}} added in CALCITE-6587.

> Support JDK 23 and Guava 33.3.0 in Avatica

>                 Key: CALCITE-6588
>                 URL: https://issues.apache.org/jira/browse/CALCITE-6588
>             Project: Calcite
>          Issue Type: Improvement
>          Components: avatica
>            Reporter: Julian Hyde
>            Priority: Major
>             Fix For: avatica-1.26.0
>
>
> Support JDK 23 and Guava 33.3.0-jre, which are the latest available versions.
> The lower bound has not changed: Avatica supports JDK down to 8, and Guava 
> down to 19.0.
> We will need to remove use of the {{getSubject}} method, which since JDK 23 
> throws:
> {noformat}
> Caused by: java.lang.UnsupportedOperationException: getSubject is supported 
> only if a security manager is allowed
>       at java.base/javax.security.auth.Subject.getSubject(Subject.java:347)
>       at 
> org.apache.calcite.avatica.server.SubjectPreservingPrivilegedThreadFactory.newThread(SubjectPreservingPrivilegedThreadFactory.java:43)
> {noformat}
> The method has been deprecated for a while, but the deprecation did not cause 
> a build failure, due to CALCITE-5136.
