------------------------------------
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?
