Karen Lease commented on CAMEL-18002:
-------------------------------------
I believe I found the reason for this. In fact, the problem does not seem to be
in the NettyHttpSimpleUriParametersTest but rather in
NettyHttpSimplePooledExchangeTest.testTwo() which makes 2 requests. In the
second one, the completion method which should release the allocated ByteBuffer
is not called.
I found this is due to the Exchange from the first request being reused and the
completion being put on it's UoW queue which is then overwritten.
I've proposed a PR which solves this in local testing.
For some reason, the leak does not appear in the test class where it actually
occurs, even when setting ResourceLeakDetector.Level.PARANOID on the test. I
don't have an explanation for this.
