[ https://issues.jboss.org/browse/JASSIST-260?page=com.atlassian.jira.plugi... ] Rafael Campos updated JASSIST-260: ---------------------------------- Steps to Reproduce: Stack frame corruption after writing to attribute contain on class that contains method with injected code via {code:java} CtMethod.insertAfter(String src) {code} This writing happens inside of the injected code src it self. Example: {code:java} public class Animal { public String ret; public AnimalRoles(){ ret = "Before"; } public String hello() { return ret; } public String die(String age) { return ""; } } {code} {code:java} // Somehow get the method hello from Animal into a var name methodHello method.insertAfter("this.ret = \"After\";"); {code} {code:java} // Call the method hello in a fresh Animal instance Animal a = new Animal(); System.out.println(a.hello()); System.out.println(a.ret); {code} Result: Before After Expected: After After Debugging the program a in the method hello it is possible to observe the following message: !Image1.png|thumbnail! Also tested with previous versions of javaassist from 3.12.1.GA until 3.20.0GA and all yield the same result. was: Stack frame corruption after writing to attribute contain on class that contains method with injected code via {code:java} CtMethod.insertAfter(String src) {code} This writing happens inside of the injected code src it self.
