What's changed?

• When the CachingMavenRecipeBundleResolver is closed, it now forces the closing of all cached MavenRecipeBundleResolver instances.
• Add cached resolver connection leak detection
• Rethrow first exception when closing all cached resolvers

What's your motivation?

We observed file handle leaks on Windows that were later throwing exceptions in CI tests.
