Forms Java Security

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, 7.0, 6u19+, 8.0

SYMPTOMS

While attempting to run Java based applet or application, a security warning dialog box appears:

Block potentially unsafe components from being run?

Java has discovered application components that could indicate a security concern. 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.
