Error in render Phase?

Vincenzo Tresoldi

Hello, guys I'm not sure that this problem is JSF or wildFly issue. I'm interested to know if anyone has encountered this problem

Only on Linux never in Windows

O.S RedHat CentOS 6.6

WildFly 10.1

Mojarra 2.2.13

Sometime application lose render capability (pages aren't builted properly on server) and this is an stack a part of stacktrace

java.lang.NullPointerException

at com.sun.faces.application.resource.ResourceHelper$ELEvaluatingInputStream.close(ResourceHelper.java:856)

at java.io.BufferedInputStream.close(BufferedInputStream.java:483)

...

at javax.faces.application.ResourceHandlerWrapper.handleResourceRequest(ResourceHandlerWrapper.java:153)

at javax.faces.webapp.FacesServlet.service(FacesServlet.java:655)

Watching GrepCode I found the piece of code that throw the exception

@Override

851 public void More ...close() throws IOException {

852

853 if (endOfStreamReached && !expressionEvaluated) {

854 info.disableEL();

855 }

856 inner.close();

857 super.close();

858

859 }

Where inner was teorically setted on

public More ...ELEvaluatingInputStream(FacesContext ctx,

682 ClientResourceInfo info,

683 InputStream inner) {

684

685 this.inner = inner;

686 this.info = info;

687 this.ctx = ctx;

688

689 }

Do you have any suggestion? Some timeout, some extra configuration or tips on linux system?

It's possible to catch the Exception and reinitialize in some way the application?

Thanks to everyone

Vincenzo
