When Health check written in Java fails, log information is unclear

Versions used

Akka version: 2.6.13
Akka-management: 1.0.9

Expected Behavior

When having custom health check written in Java e.g. com.test.HealthCheck, which fails, then expected behavior when asking for readiness would to see following log:

Not Healthy: Check [com.test.HealthCheck] not ok

Actual Behavior

Currently, log is:

Check [akka.management.internal.HealthChecksImpl$$Lambda$1599/0x0000000100e84040] not ok

Using Scala Function0<Future<Boolean>> instead of Supplier can be used as workaround.

Internally it looks that Java Supplier is converted and then the name of the original class is gone.
