CryptoHelper.java not able to detect socket close due to which application hang infinitely

[beingtech]

Many times when client disconnect and application is trying to send data application hang infinitely

Cause :- CryptoHelper.java

Line 417 :- SSLEngineResult result = _engine.wrap(src, _netSendBuffer); This is returning => result.getStatus() == Status.BUFFER_OVERFLOW

Line 435 :- if (_socketChannel.write(_netSendBuffer) <= 0) This is throwing following

java.io.IOException: An established connection was aborted by the software in your host machine at java.base/sun.nio.ch.SocketDispatcher.write0(Native Method) at java.base/sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:54) at java.base/sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:132) at java.base/sun.nio.ch.IOUtil.write(IOUtil.java:76) at java.base/sun.nio.ch.IOUtil.write(IOUtil.java:53) at java.base/sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:532) at com.refinitiv.eta.transport.CryptoHelper.write(CryptoHelper.java:435) at com.refinitiv.eta.transport.CryptoHelper.write(CryptoHelper.java:464) at com.refinitiv.eta.transport.EncryptedSocketHelper.write(EncryptedSocketHelper.java:25) at com.refinitiv.eta.transport.RsslSocketChannel.write(RsslSocketChannel.java:671) at com.refinitiv.eta.transport.RsslSocketChannel.writeGatheringByteArray(RsslSocketChannel.java:2737) at com.refinitiv.eta.transport.RsslSocketChannel.flushInternal(RsslSocketChannel.java:2660) at com.refinitiv.eta.transport.RsslSocketChannel.writeWithBuffersQueued(RsslSocketChannel.java:2506) at com.refinitiv.eta.transport.RsslSocketChannel.write(RsslSocketChannel.java:2268) at com.refinitiv.eta.valueadd.reactor.Reactor.submitChannel(Reactor.java:4388) at com.refinitiv.eta.valueadd.reactor.Reactor.submitChannel(Reactor.java:4498) at com.refinitiv.eta.valueadd.reactor.ReactorChannel.submit(ReactorChannel.java:829) at com.refinitiv.ema.access.OmmIProviderImpl.submit(OmmIProviderImpl.java:1087) at com.refinitiv.ema.access.OmmIProviderImpl.submit(OmmIProviderImpl.java:690)

Line 442 :- catch (IOException e) above exception is catched by line 442 and control again goes to line 417 and again same flow repeat

Above flow is getting repeated infinitely which lead to application get hanged as thread as already acquired writelock and it will never get released.
