Upgrade OpenTelemetry libraries to 1.61.0 / 2.27.0#4773
Merged
Conversation
…togramOptions The runtime-telemetry-java8 module's individual observer classes (Classes, Cpu, GarbageCollector, MemoryPools, Threads, ExperimentalBufferPools) were removed in opentelemetry-instrumentation 2.27.0; switch to the unified opentelemetry-runtime-telemetry module's RuntimeTelemetry builder. Also replace the Aggregation.explicitBucketHistogram(List<Double>) overload deprecated in opentelemetry-java SDK 1.60.0 with the new ExplicitBucketHistogramOptions form.
