There might be a problem in java language resulting in LARA reporting: “Could not recover key from keystore.” when attempting to connect to NM B2B services.

The log will contain further detail of the error:

Caused by: java.security.InvalidKeyException: Invalid RSA private key
	at sun.security.rsa.RSAPrivateCrtKeyImpl.parseKeyBits(Unknown Source)
	at sun.security.pkcs.PKCS8Key.decode(Unknown Source)

Caused by: java.io.IOException:DerInputStream.getLength(): Redundant length bytes found

There is a potential issue between the Java JRE versions 1.8.0-121 onwards and the NM B2B Certificates (issued by Globalsign).

This impacts all B2B versions on OPS and PRE-OPS.

If you are using any of these Java versions from 121 onwards (e.g. 1.8.0-121, 1.8.0-141, etc.), LARA may not be able to operate correctly, as B2B transactions could be blocked.

If this error occurs then a request for new openSSL version of the NM certificate from the NM CSO (mailto:NM.cso.help-desk@eurocontrol.int) is required. The new certificate will have had the redundant bytes removed from it.

Please reference the java bug reports when emailing: (https://bugs.openjdk.java.net/browse/JDK-8175251, http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8178396)
