The ecdsa-with-Specified AlgorithmIdentifier for signatures is unusual in that it encodes the hash algorithm separately in the parameters instead of as part of the main ObjectIdentifier. Special code is required to recognize that and construct the correct algorithm name when verifying e.g. X509Certificate containing such signatures. That code was added to JDK 6 as part of 6414980.

This RFE is used to track a potential backport of that particular issue (but not the larger ECC related changes) to earlier releases.
