Troubleshooting
Problem
The java.exe process is terminated on Windows 10 / Windows 2019 environments unexpectedly by Windows CFG (Windows Control Flow Guard)
Symptom
The WebSphere server starts and writes only a few lines in the SystemOut.log, and then logging just stops, the SystemOut.log is truncated.
The java.exe process goes away; there are no dump files generated (javacores, snap, or core dump files) and no errors in the Event Viewer logs
Cause
The Windows CFG prevents the WebSphere Application Server embedded java.exe to be executed.
Resolving The Problem
Open a PowerShell window as administrator
Run the following and replace the <WAS_HOME> with the WebSphere Application Server installation directory path.
For WebSphere Application Server v8.5.5.x
Set-ProcessMitigation -name "<WAS_HOME>\java\jre\bin\java.exe" -disable CFG
For WebSphere Application Server v9.0.5.x
Set-ProcessMitigation -name "<WAS_HOME>\java\8.0\jre\bin\java.exe" -disable CFG
Once the Windows CFG is disabled for the WebSphere Application Server embedded Java, try to start the application server again.
