[jboss-jira] [JBoss JIRA] Closed: (JASSIST-138) CHECKCAST of javassist.bytecode.analysis.Executor.execute() is broken

CHECKCAST of javassist.bytecode.analysis.Executor.execute() is broken --------------------------------------------------------------------- Key: JASSIST-138 URL: https://issues.jboss.org/browse/JASSIST-138 Project: Javassist Issue Type: Bug Affects Versions: 3.12.0.GA Reporter: Yu Kobayashi Assignee: Shigeru Chiba Fix For: 3.15.0.GA At execute(MethodInfo method, int pos, CodeIterator iter, Frame frame, Subroutine subroutine) of javassist.bytecode.analysis.Executor, CHECKCAST is this. case CHECKCAST: verifyAssignable(Type.OBJECT, simplePop(frame)); frame.push(typeFromDesc(constPool.getClassInfo(iter.u16bitAt(pos + 1)))); break; However, constPool.getClassInfo() doesn't returns its descriptor. To fix this, please change it to frame.push(typeFromDesc(constPool.getClassInfoByDescriptor(iter.u16bitAt(pos + 1)))); and add this to javassist.bytecode.ConstPool. public String getClassInfoByDescriptor(int index) { ClassInfo c = (ClassInfo)getItem(index); if (c == null) return null; else { String className = getUtf8Info(c.name); if (className.charAt(0) == '[') { return className; } else { return Descriptor.of(className); } } }
