[jboss-jira] [JBoss JIRA] (JGRP-2337) DiagnosticsHandler without reflection

Bela Ban created JGRP-2337: ------------------------------ Summary: DiagnosticsHandler without reflection Key: JGRP-2337 URL: https://issues.jboss.org/browse/JGRP-2337 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 4.1.0 Probe.sh sends commands to cluster nodes, and they are handled by each node's DiagnosticsHandler. {{op}} and {{jmx}} commands are handled via reflection. However, reflection is not allowed by the GraalVM running in native mode, unless all attributes and methods of all protocols would be listed in a JSON file. This is apparently very costly as the native image builder creates a transitive closure over all classes whose methods and/or fields are listed in the JSON file, and thus includes too many classes in the native image. Investigate creating a {{ProbeHandler}} for {{"jmx""}} and {{"op"}} commands, which does not use reflection. Offline creation and compilation: point to a list of protocols for which code is generated (an alternative ProbeHandler class). This class is then instantiated and set in the channel at runtime by the application -- This message was sent by Atlassian Jira (v7.12.1#712002)
