[jira] [Created] (CALCITE-6590) Remove use of Java SecurityManager in Avatica

Julian Hyde created CALCITE-6590:
------------------------------------

             Summary: Remove use of Java SecurityManager in Avatica
                 Key: CALCITE-6590
                 URL: https://issues.apache.org/jira/browse/CALCITE-6590
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
             Fix For: 1.26.0


Remove use of Java SecurityManager in Avatica.

Running Avatica on JDK 23 (or JRE 23) we get the following runtime errors:
{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}
We were warned - methods {{getSubject}} have been deprecated since JDK 18.

The message "getSubject is supported only if a security manager is allowed" implies that another solution would be to enable a security manager (including during tests, and when Avatica is used in Calcite's tests). Should we consider that?
