…lsar processes - allows Netty to use reflection access on JDK9+ - fixes jvm_memory_direct_bytes_used Prometheus metric for Bookkeeper (Bookie). The direct memory usage metrics are disabled in Bookie on JDK11 unless -Dio.netty.tryReflectionSetAccessible=true is used. - enables Netty to use more efficient byte buffer implementation such as UnpooledUnsafeNoCleanerDirectByteBuf in JDK9+ (JDK 11 in this case). This is already used in JDK8. In JDK9+, it is necessary to set -Dio.netty.tryReflectionSetAccessible=true to use UnpooledUnsafeNoCleanerDirectByteBuf. This is necessary for preventing performance regressions in this area. upstream PR apache#11138

Prometheus metric for Bookkeeper (Bookie). The direct memory usage metrics are disabled in Bookie on JDK11 unless-Dio.netty.tryReflectionSetAccessible=true
is used.-Dio.netty.tryReflectionSetAccessible=true
to use UnpooledUnsafeNoCleanerDirectByteBuf. This is necessary for preventing performance regressions in this area.Modifications
-Dio.netty.tryReflectionSetAccessible=true
JVM option by default to all pulsar process started withbin/pulsar
