No longer able to launch the iDRAC console after upgrading Java -
Description
The follow error is displayed when launching applications signed with the MD5withRSA or MD5withDSA algorithms after upgrading Java:Unable to launch application.Unsigned application requesting unrestricted access to system. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned: http://example.net/ExampleApplication.jar -
Cause
Applications signed with the MD5withRSA or MD5withDSA algorithms are treated as unsigned by Java starting with the Java 8 Update 131 release.

Résolution
WORKAROUND:
Edit the "jdk.jar.disabledAlgorithms" section of the java.security file and remove the weak algorithm that DRAC is using, so that it will not be blocked.The file is located here: C:\Program Files (x86)\Java\jre1.8.0_131\lib\security\java.security
This workaround should be considered "at your own risk" and is not officially endorsed or supported by One Identity.
SOLUTION:
The solution is to upgrade the version of iDRAC software on the appliance, however, this may require an RMA replacement of the hardware. Please discuss with One Identity Support to determine the best course of action.
