Ensuring Application and Applet Security when Mixing Signed and Unsigned Code
Java 6 Update 21
As of the Java SE 6 Update 19 release, when both signed and unsigned code are detected in a Java Web Start application or applet, a warning dialog is raised. As of this release, an enhancement is added allowing some sandboxed jar files to be signed without having to change the JNLP file to request the
all-permissions
security model. See Mixing Signed and Unsigned Code for more information.Security Exception Upon Drag-and-Drop
Drag-and-drop would, under certain circumstances, result in a null value being passed instead of the expected data.
Java SE 6u21 provides a fix that lets drag-and-drop operations succeed for signed applications or applications with the
accessClipboard
permission granted.Restoration of the Company Name Property Affecting Eclipse Users
As part of Oracle's rebranding of Sun's products, the Company Name property of the java.exe file, the executable file containing Oracle's JRE for Windows, was updated from 'Sun Microsystems' to 'Oracle' in Java SE 6u21.
After the updated JRE was posted, it was reported that the change affected Eclipse users by causing it to hang when starting Eclipse after updating to the rebranded JRE. A workaround was quickly identified and posted on Eclipse's website, but a wide distribution of the rebranded JRE executable could negatively impact many Eclipse users. World of warships free experience hack.
Java
In consideration to Eclipse and other potentially affected users, Oracle has restored the Windows Company Name property value to 'Sun Microsystems'. This value will be changed to 'Oracle' in JDK 7.
The change affected only the Windows version of the JRE, not the versions for Solaris and Linux. To accommodate this update, the Windows build version will increase from Java SE 6u21-b06 to Java SE 6u21-b07.
Update for JDK Installation Failure for Brazillian Portuguese
Nvidia nforce drivers windows 10. The JDK installation failure for Brazillian Portuguese issue has been fixed in this release.
The installation of the Java SE 6u21 JDK package resulted in a failure for Brazillian Portuguese locale with the generation of 'Error applying transforms. Verify that the specified transform paths are valid' error message. However, this was not an issue for installing the JRE, since the JRE was localized for Brazillian Portuguese.

Java SE 6 Update 21 does not contain any additional fixes for security vulnerabilities to its previous release, Java SE 6 Update 20. Users who have Java SE 6 Update 20 have the latest security fixes and do not need to upgrade to this release to be current on security fixes.
