If you really cannot move up to at least the Juno release then the 2
following options area available:
1) remove the signatures from the jars and place them on your own update
sight to install from ... or
2) patch equinox (org.eclipse.osgi) with
https://bugs.eclipse.org/bugs/show_bug.cgi?id=378155

Subject: [cross-project-issues-dev] To be able to install newly
signed plug-in on Helios and Indigo
Sent by:cross-project-issues-dev-boun...@eclipse.org
Hello,
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
2.16.840.1.101.3.4.2.1
at
org.eclipse.osgi.internal.signedcontent.PKCS7Processor.findDigest(PKCS7Processor.java:87)

org.eclipse.osgi.internal.signedcontent.PKCS7Processor.processSignerInfos(PKCS7Processor.java:311)

at
org.eclipse.osgi.internal.signedcontent.SignedBundleHook.getSignedContent(SignedBundleHook.java:247)
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 [1]. 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?
