Steps to reproduce this issue

Resource leak, non-deterministic.

What you expected to happen

CompositeInputStream.close() should attempt to close all underlying streams, even if one close() throws. After trying all closes, it should throw the first IOException and attach later close failures as suppressed exceptions (if any).

This prevents partial cleanup and potential resource leaks.

Anything else

Current behavior: CompositeInputStream.close() stops at the first IOException, leaving remaining streams unclosed.

Frequency: Every time an underlying stream’s close() throws.

Proposed fix: Wrap each close() in try/catch while draining the queue, collect the first IOException, suppress subsequent failures, and throw after attempting all closes.
