Doc Text:
It was found that a prior countermeasure in Apache WSS4J for Bleichenbacher's attack on XML Encryption (CVE-2011-2487) threw an exception that permitted an attacker to determine the failure of the attempted attack, thereby leaving WSS4J vulnerable to the attack. The original flaw allowed a remote attacker to recover the entire plain text form of a symmetric key.

Description Vasyl Kaigorodov 2015-02-11 05:47:44 EST 
Apache WSS4J 1.6.5 contained a countermeasure for Bleichenbacher's attack on XML Encryption, where the PKCS#1 v1.5 Key Transport Algorithm is used to encrypt symmetric keys as part of WS-Security. In particular, the fix avoided leaking information on whether decryption failed when decrypting the encrypted key or decrypting the message data.

However, it is still possible to craft a message such that an attacker can tell where the decryption failure took place, and hence WSS4J is vulnerable to the original attack. 

See here for more information on the original fix for WSS4J 1.6.5:
