WildFly does not shutdown after "Ctrl+C" on Java 15 (Windows)

[Wolfgang]

Hi,

when running WildFly with Java 15 (using "standalone.bat" or "standalone.ps1"), it does not shutdown on latest Windows 10 when "Ctrl+C" is pressed in the console.

It works with Java 1.8.

The output is:

12:54:53,005 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: WildFly Full 23.0.0.Final (WildFly Core 15.0.0.Final) started in 3242ms - Started 319 of 558 services (344 services are lazy, passive or on-demand)

....CTRL+C is pressed.....

After the last output line, the command prompt is NOT shown, and the message "Batchvorgang abbrechen (J/N)?" ("Terminate batch job") should be printed, but this does not happen. The message is shown after "CTRL+C" is pressed another time.

This happens with all older WildFly versions that I tested, at least back to WildFly 11.

As I cannot create a thread dump using CTRL+BREAK in this situation, it might also be a Java problem. But a small sample console app was canceled by CTRL+C.

Is this a known issue? Is it worth a JIRA ticket?

Best regards

Wolfgang

Hello Wolfgang,

   WildFly is not supported on JDK15. The latest supported JDK for WildFly is JDK 13.

This issue does not occur in my environment

OK, I could make it work: the environment variable "JAVA_HOME" has to be set:

JAVA_HOME=C:\Program Files\Java\jdk-15.0.2\

If it is not set, "java --version" still prints the same output as in your screenshot, but the hang occurs.

The command "where java" prints this:

C:\Program Files\Common Files\Oracle\Java\javapath\java.exe
C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe

Those files are 646 KB exe files.

I don't understand why this happens, but it works now.

Best regards

Wolfgang
