> Please find below a fix for:
> 8265367: [macos-aarch64] 3 java/net/httpclient/websocket tests fail with "IOException: No buffer space available"
> The Pending* websocket tests create a server that accepts sockets to create a websocket, but never read data from the websocket in order to get the client side to block once the buffers are full.
> Unfortunately, the PendingOperations:cleanup methods was not called after each test methods invocations, causing sockets to leak and relying on the gc to cleanup.
> This caused an "IOException: No buffer space available" to be raised intermittently but reliably (1 run out of 50 in PendingTextPingClose).
> The fix makes sure that cleanup() is called appropriately after each test method invocation.
> It also tweaks PendingTextPingClose - which seemed to be failing more frequently - to use smaller send and receive buffers in order to reach the point at which the client bocks more quickly and avoid wasting system resources.
