FULL PRODUCT VERSION :

ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
One of the constructors of EncryptedPrivateKeyInfo expects an algorithm name (as a string).
If the string is not a valid Object Identifier, but contains dots, the constructor throws NumberFormatException, when it should throw NoSuchAlgorithmException.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Calling a the constructor with a string such as "1.2.3.", or "1.2.3.a", or "a.a" causes NumberFormatException to be thrown. For instance
EncryptedPrivateKeyInfo epki = new EncryptedPrivateKeyInfo("aa.aa", new byte[8]);

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The exception NoSuchAlgorithmException should be thrown, like
java.security.NoSuchAlgorithmException: unrecognized algorithm name: aa.aa
at sun.security.x509.AlgorithmId.get(AlgorithmId.java:105)
at javax.crypto.EncryptedPrivateKeyInfo.<init>(DashoA12275)
at TestOid.main(TestOid.java:16)
ACTUAL -
The exception NumberFormatException is thrown:
Exception in thread "main" java.lang.NumberFormatException: For input string: "aa"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:447)
at java.lang.Integer.valueOf(Integer.java:553)
at sun.security.util.ObjectIdentifier.<init>(ObjectIdentifier.java:69)
at sun.security.x509.AlgorithmId.algOID(AlgorithmId.java:312)
at sun.security.x509.AlgorithmId.get(AlgorithmId.java:98)
at javax.crypto.EncryptedPrivateKeyInfo.<init>(DashoA12275)
at TestOid.main(TestOid.java:16)

REPRODUCIBILITY :
This bug can be reproduced always.
