http://issues.apache.org/bugzilla/show_bug.cgi?id=43367 Summary: MethodGen.setMaxLocals() calculates too small max locals, which results in a ClassFormatError when loading the modified class Product: BCEL Version: unspecified Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Main AssignedTo: bcel-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Revision 574984 (trunk) When a local variable is added to a method, the max_locals are incremented in addLocalVariable (set to slot + size of type). However, when no other transformations are made, and setMaxLocals() is called, the bytecode is searched for the max variable index, and max_locals set to that index + size of that entry. The old max_locals which was set by adding the field is overwritten by this number. If the LocalVariableTable for that method exists, the Java VM won't load the class, because the max_locals determined by bcel is smaller than the max locals determined from the localvariabletable => ClassFormatException. -- 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]
