Chapter 3. Unsupported features and deprecated features

Support for some technologies is removed due to the high maintenance cost, low community interest, and better alternative solutions. The following features are not supported in JBoss EAP XP 5.0:

MicroProfile Metrics

MicroProfile Metrics is no longer supported, and is replaced by Micrometer.

MicroProfile OpenTracing

MicroProfile OpenTracing is no longer supported, and is replaced by OpenTelemetry Tracing.

Red Hat OpenShift Streams for Apache Kafka

Since Red Hat no longer offers Red Hat OpenShift Streams for Apache Kafka (RHOSAK), the MicroProfile Reactive Messaging with Kafka quickstart has been updated to not demonstrate connecting to RHOSAK.

Snappy compression disabled for Windows systems

JBoss EAP XP 5.0 does not support Snappy compression on Windows platforms for the MicroProfile Reactive Messaging Kafka connector. The Kafka connector for MicroProfile Reactive Messaging introduced Snappy compression in JBoss EAP XP 4.0.2 using Snappy version 1.1.8.4. However, Java Snappy compression was removed in version 1.1.9.0 of Snappy due to data corruption concerns. JBoss EAP XP 5.0 now uses the latest version of Snappy, 1.1.10.5, which uses native code for compression. The Red Hat build of the Snappy jar includes only the Linux natives.

MicroProfile Reactive Messaging Kafka client

The MicroProfile Reactive Messaging Kafka client available with JBoss EAP XP 5.0 is not supported on Windows platforms.
