Coherence .Net Client 3.7.1.3 Crashes When Timeout Occurs - Is it OK to have different versions of .Net Coherence Clients & Servers (Doc ID 1517259.1)

Goal

Coherence .Net Client 3.7.1.3 crashes when timeout occurs

Client throws following Exception when there's a request timeout:

System.ArgumentOutOfRangeException: Non-negative number required.
Parameter name: millisecondsTimeout
  at Tangosol.Net.Messaging.Impl.Request.RequestStatus.WaitForResponse(Int64 millis) in c:\Coh\workspace\Coh-NET-3.7.1\dev\release.net\coherence-net-v3.7.1\src\Coherence\Net\Messaging\Impl\Request.cs:line 595

System.Threading.ThreadInterruptedException : Thread was interrupted from a waiting state.
at System.Threading.WaitHandle.WaitOneNative(SafeHandle waitableSafeHandle, UInt32 millisecondsTimeout, Boolean hasThreadAffinity, Boolean exitContext)

During research, it is found that the root cause is a Bug in Coherence code in Tangosol.Net.Messaging.Impl.Request.RequestStatus.WaitForResponse(Int64 millis)
there's a missing break statement after the RequestTimeoutException is created (it never gets thrown)

   while (!this.IsClosed)
   {
       if (start < (long)0)
       {
           DateTime utcNow = DateTime.UtcNow;
           start = utcNow.Ticks / (long)10000;
       }
       try
       {
           Monitor.Wait(this, (int)remain);
       }
       catch (Exception exception1)
       {
           Exception caught = exception1;
           e = caught;
           break;
       }
       if (this.IsClosed)
       {
           break;
       }
       DateTime dateTime = DateTime.UtcNow;
       long num = remain - Math.Max(dateTime.Ticks / (long)10000 - start, (long)0);
       remain = num;
       if (num > (long)0)
       {
           continue;
       }
       e = new RequestTimeoutException(string.Concat("request timed out after ", millis, " millis"));
   }

Due to Business Requirements, Logic updating Client/ Server Coherence versions may be postponed.  Coherence Server is running 3.7.1.3.
Can we request Oracle to provide 3.7.1.3_Patch?

Application slows down, Thread.Interrupt has devastating impact on the Client.

See the following Error:

It originates from system assembly: Monitor.Wait(this, (int)remain);

It occurs even though, we specify “positive” timeout values:
