Oracle Java SE 7 and earlier, and OpenJDK 7 and earlier, computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against the MurmurHash3 algorithm, a different vulnerability than CVE-2012-2739.

CVE-2012-5373 [MEDIUM] CVE-2012-5373 java: Murmur hash function collisions (oCERT-2012-001)
CVE-2012-5373 java: Murmur hash function collisions (oCERT-2012-001)
A denial of service flaw was found in the Murmur hash function implementation, as being used by various Java implementations. A specially-crafted set of keys could trigger Murmur hash function collisions, which degrade hash table items insert performance by changing hash table operations complexity from an expected/average O(n) to the worst case O(n^2). Reporters were able to find colliding strings efficiently using equivalent substrings.
As various web application frameworks for Java automatically pre-fill certain arrays with data from the HTTP request (such as GET or POST parameters) for Java web applications, a remote attacker could use this flaw to make the Java virtual machine to use an excessive amount of CPU time
