Error : Java has discovered application components that could indicate a security concern
This article applies to:
- Platform(s): All Platforms
- Java version(s): 6.0, 6u19+
SYMPTOMS
While attempting to run Java based applet or application, a security warning dialog box appears:
Java has discovered application components that could indicate a security concern ... Block potentially unsafe components from being run?
The application contains both signed and unsigned code. Contact the application vendor to ensure that it has not been tampered with.
The application contains both signed and unsigned code. Contact the application vendor to ensure that it has not been tampered with.
CAUSE
Signed Java Web Start applications and applets that contain signed and unsigned components could potentially be unsafe unless the mixed code was intended by the application vendor. As of the Java SE 6 Update 19 release, when a program contains both signed and unsigned components, a warning dialog is raised.
SOLUTION
In the security dialog, if the user clicks Yes, it blocks potentially unsafe components from running, and the program may terminate. If the user clicks the No button, the application or applet continues execution.
Raising a warning is the default behavior, but there are options available for users to manage this situation.
You can manage how mixed code programs are handled through the Java Control Panel.
