# Harness Java client waitForInitialization hangs forever with a bad API key

## What's going on

Calling waitForInitialization() with an invalid API key never returns and never throws. The retry interceptor kept retrying and hit an IllegalStateException about the previous response still being open, so the wait() never woke up.

## The verified fix

Fixed in the SDK via PR #137. Update the ff-java-server-sdk past that fix and a bad API key fails fast instead of hanging forever.
