Subject [jira] [Commented] (WSS-555) AES-GCM does not work with IBM JCE 1.7

-------------------------------------

Thanks colm for your response! The above error I was getting while using wss4j dom api to
encrypt/decrypt message using AES-GCM. But I got it working by upgrading JVM 1.7 SR3 to JVM
SR9, looks like JCE issue.

But when try to use stax api to encrypt/decrypt messages with AES-GCM then I get following
error

I think this is due to incorrect (IvParameterSpec) parameter used in AbstractEncryptOutputProcessor.java
for GCM.
