|[cross-project-issues-dev] To be able to install newly signed plug-in on Helios and Indigo|
We are not able to install newly signed plug-ins on Helios, and Indigo. We get the following error (during the installation of a signed plug-in):
Caused by: java.security.NoSuchAlgorithmException: No algorithm found for 2.16.8188.8.131.52.4.2.1
This error happens because the class ‘PKCS7Processor’ embedded in Helios and Indigo isn’t able to deal with SHA-256. SHA-256 is used since Java-1.7 to sign . I assume that the signing service has been updated to Java-1.7.
From the release train point of view this seems to be a good thing. But my company integrates EMF Facet and MoDisco into its own product and some of our clients are still using Helios and Java-1.5!
Does anybody have any advice to be able to install newly signed plug-in on Helios and Indigo?
