Problem Description: 
Whenever we restart ColdFusion we get the following error message in coldfusion-error.log.

Steps to Reproduce:
1) Restart ColdFusion (or a ColdFusion instance);
2) Open the log file, coldfusion-error.log, in a text editor and examine the lines corresponding to the restart.

Actual Result:
You will see the following error message:

Jul 26, 2018 11:01:18 AM org.apache.coyote.AbstractProtocol stop
INFO: Stopping ProtocolHandler ["ajp-nio-8026"]
Exception in thread "Thread-11" java.lang.NoClassDefFoundError: java/nio/channels/FileLock

Caused by: java.lang.ClassNotFoundException: java.nio.channels.FileLock
	at coldfusion.bootstrap.BootstrapClassLoader.loadClass(
	at java.lang.ClassLoader.loadClass(

Expected Result:
No such error message.

Any Workarounds:
Not applicable



We are uncertain as to the effect of NoClassDefFoundError exception on java.nio.channels.FileLock. It might be negligible. But then again it might be critical.

Hi Bakia I don't see this error of CF restart. I am verifying this on CF2016. Could you please check that any piece of code is generating this error and let me know about the same. Thanks Poonan

Hi Poonam, Thank you for taking a look at this ticket. I am withdrawing it, as I have been unable to reproduce the issue consistently. Nevertheless, I am searching for a solution or workaround myself. Kind regards, Bakia
