http://issues.apache.org/bugzilla/show_bug.cgi?id=41069 Summary: array elements' type not always verified by JustIce Product: BCEL Version: unspecified Platform: Macintosh OS/Version: Mac OS X 10.4 Status: NEW Severity: normal Priority: P3 Component: Main AssignedTo: bcel-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] The following class is accepted by JustIce (BCEL 5.2), whereas Sun verifier (correctly) rejects it: Compiled from "Test.java" public class Test extends java.lang.Object{ public Test(); Code: 0: aload_0 1: invokespecial #9; //Method java/lang/Object."<init>":()V 4: return public static void main(java.lang.String[]); Code: 0: aload_0 1: iconst_0 2: caload 3: return } In the "main" method we are trying to read a char from an array of Strings and this is of course type- incorrect. My take on the solution is that in the org.apache.bcel.verifier.structurals.InstConstraintVisitor class, in the visitCALOAD method, there are only two checks being made: whether the index is of int type, and whether there is really an array on the stack. What is missing is the check, whether the array holds element of 'char' type. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
