OutOfMemoryError after upgrade to Spring Boot 3.1.4 #37798

An issue that we don't feel is valid
After upgrading to Spring Boot 3.1.4. we are experiencing OutOfMemoryErrors. I see an ever increasing number of
io.micrometer.tracing.otel.bridge.OtelTraceContext
/SpanFromSpanContext
. Obviously, we are using theio.micremter.tracing
Otel bridge. Downgrading to Spring Boot 3.1.3 resolves the issue immediately. For microservices with high load this leads to OoME within a couple of hours. For microservices with low load, this is not really relevant.The trace contexts are retained from a thread local variable (which one I have not been able to find out yet). I assume this has to do with the dependency update as requested by #37262. I am still opening the issue here because it affects the latest 3.1.x Spring Boot version.
