Micrometer: Failed to send metrics to opentsdb

[exploder86]

Hi there,
After switching to 1.5.1 micrometer-registry-opentsdb we faced with error. It's look like a bug:

19-05 22:09:31:335 WARN [OpenTSDBMeterRegistry] failed to send metrics to opentsdb
java.lang.ClassCastException: class io.micrometer.core.instrument.internal.DefaultLongTaskTimer cannot be cast to class io.micrometer.opentsdb.OpenTSDBTimer (io.micrometer.core.instrument.internal.DefaultLongTaskTimer and io.micrometer.opentsdb.OpenTSDBTimer are in unnamed module of loader 'app')

@exploder86 It sounds like you might have version misalignment. Can you check your runtime classpath to ensure that all (micrometer-core, micrometer-registry-opentsdb) are all at 1.5.1?

If this is a Spring Gradle project, this is commonly caused by the Spring dependency management plugin which will pull down the micrometer-core version unless you set the micrometer.version property or include a direct dependency on micrometer-core:1.5.1.

This has been resolved via https://github.com/micrometer-metrics/micrometer/pull/2075.

@exploder86 Please try 1.5.2-SNAPSHOT.

It's worked with 1.5.2-SNAPSHOT
Thanks!
