Disable Hibernate L2 cache in openmrs-runtime.properties by setting hibernate.cache.use_second_level_cache=false. This prevents Infinispan from initializing, avoiding the Java 21+ incompatibility where Subject.getSubject() throws UnsupportedOperationException (removed entirely in Java 24 via JEP 486). OpenMRS's HibernateSessionFactoryBean merges runtime properties into the Hibernate config, so this single property prevents Infinispan's InfinispanRegionFactory from ever being created. For a standalone/demo distribution the L2 cache performance impact is negligible. See PR #112 for an alternative approach that keeps L2 caching by patching the Infinispan WAR. Also sync the Bootstrap.java default vm_arguments with the runtime properties by adding the missing --add-opens flag. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Problem
Infinispan 13.0.22 (bundled in OpenMRS Core 2.8.4) calls
Subject.getSubject()during initialization, which throwsUnsupportedOperationExceptionon Java 21.0.4+ and is removed entirely in Java 24 (JEP 486).Fix
Disable Hibernate L2 cache via
hibernate.cache.use_second_level_cache=falsein the runtime properties. OpenMRS'sHibernateSessionFactoryBeanmerges runtime properties into Hibernate config, so this prevents Infinispan from ever initializing.This is the simpler alternative to #112 (which patches the Infinispan WAR to keep L2 caching). For a standalone/demo distribution the performance impact is negligible.
Changes
src/main/config/openmrs-runtime.properties: Addhibernate.cache.use_second_level_cache=falsesrc/main/java/org/openmrs/standalone/Bootstrap.java: Sync default vm_arguments to include--add-opens=java.base/java.lang=ALL-UNNAMEDCompatibility
Works on Java 21, 24, 25, and all future versions (no dependency on Security Manager APIs).
