[jboss-jira] [JBoss JIRA] (JASSIST-216) A NullPointerException thrown in javassist.bytecode.analysis.ControlFlow

A NullPointerException thrown in javassist.bytecode.analysis.ControlFlow ------------------------------------------------------------------------ Key: JASSIST-216 URL: https://issues.jboss.org/browse/JASSIST-216 Project: Javassist Issue Type: Bug Affects Versions: 3.18.1-GA Reporter: Shigeru Chiba Assignee: Shigeru Chiba Priority: Minor Fix For: 3.18.2-GA, 3.19.0-GA (The original report is Maximilian Scherr.) When analyzing a method with exception handler, printing the exception handler block caused a NullPointerException here (line 248): protected void toString2(StringBuffer sbuf) { super.toString2(sbuf); sbuf.append(", incoming{"); for (int i = 0; i < entrances.length; i++) sbuf.append(entrances[i].position).append(", "); sbuf.append("}"); } It appears catcher blocks have a single predecessor (instead of 0) that is "null".
