I just got Java 8 update 351-b10 delivered to my laptop.  When I try to launch the Java application I get the following error:

Removal of the exception for JARs that are signed with certificates that do not chain back to a Root CA included by default in the JDK cacerts keystore.

Reference the "Disable SHA-1 signed jars" section of for more information.

Reference the "Disabled SHA-1 Signed JARS" section of for more information.


1. Use the OpenJDK version which is shipped with OneClick. Reference the "What are best steps to migrate from Oracle Java to OpenJDK for Spectrum OneClick?" knowledge article.

2. Use the WebApp

3. Remove the block on SHA1 in the file (highlighted in red) on the client system and re-download the JNLP file.

4. Downgrade JRE. The restriction was introduced in 8u351, so any JRE earlier will work.

This is discussed in the url's noted in the "Cause" section of this knowledge article.
