Describe the bug A clear and concise description of what the bug is.

We are using launchdarkly-java-server-sdk:6.3.0 and our pipelines are usually failing with error as

09:22:24.112 ERROR c.s.f.i.LDFeatureFlagClient    : Unable to start the LD feature flag client
java.lang.IllegalStateException: LdFeatureFlagClient not initialized after '10' seconds!

I found that I restarted my IDE(IntelliJ), flushed IntelliJ cache and even tried to console but every time the error persists. But, when I restarted the machine, error goes away. This is annoying as it is failing my release pipelines in intermittently.

To reproduce Steps to reproduce the behavior. Use launchdarkly-java-server-sdk:6.3.0 and run your tests, if you encountered with LdFeatureFlagClient not initialized after '10' seconds! you need to restart machine else the error won't go away.

Expected behavior A clear and concise description of what you expected to happen. LDClint should start within given 10 second time.

Logs If applicable, add any log output related to your problem.
