FULL PRODUCT VERSION : ADDITIONAL OS VERSION INFORMATION : Ubuntu 12.04 LTS A DESCRIPTION OF THE PROBLEM : If a call to java.security.Signature.verify(byte[] signature, int offset, int length) with offset + length > Integer.MAX_VALUE, an ArrayIndexOutOfBoundsException will be thrown instead of IllegalArgumentException. REGRESSION. Last worked in version 7 STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Run the test case. EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - Test finished silently. ACTUAL - java.lang.ArrayIndexOutOfBoundsException was thrown. ERROR MESSAGES/STACK TRACES THAT OCCUR : Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -2147483648 at sun.security.util.DerInputStream.init(DerInputStream.java:106) at sun.security.util.DerInputStream.<init>(DerInputStream.java:95) at sun.security.provider.DSA.engineVerify(DSA.java:326) at java.security.Signature$Delegate.engineVerify(Signature.java:1179) at java.security.Signature.verify(Signature.java:665) REPRODUCIBILITY : This bug can be reproduced always. ---------- BEGIN SOURCE ---------- /* * Copyright (c) 2012 Oracle and/or its affiliates.
