Dale Emery created GEODE-10185:
----------------------------------
Summary: ObjectTraverser cannot traverse a Proxy on JDK 17
Key: GEODE-10185
URL: https://issues.apache.org/jira/browse/GEODE-10185
Project: Geode
Issue Type: Improvement
Components: core
Affects Versions: 1.15.0
Reporter: Dale Emery
On JDK 17, {{ObjectTraverser}} cannot make fields of a Proxy object's class
accessible because the class is in an unopened package. JDK 17 creates proxy
classes in "dynamic" packages created by the JDK as needed. These packages
cannot be opened when starting the JVM (via {{{}--add-opens{}}}) because the
packages do not exist at that time.
{{MemoryOverheadIntegrationTest}} shows this failure in CI integration test
tasks on JDK 17.
* Example failure in CI:
[https://concourse.apachegeode-ci.info/builds/40607693]
* Test results:
[http://files.apachegeode-ci.info/builds/apache-develop-pr/geode-pr-7505/test-results/integrationTest/1648496987/]
