Buggy source:
public String toJava(int indent,BytecodeMappingTracer tracer){
  String indstr=InterpreterUtil.getIndentString(indent);
  StringBuilder buf=new StringBuilder();
  String new_line_separator=DecompilerContext.getNewLineSeparator();
  buf.append(ExprProcessor.listToJava(varDefinitions,indent,tracer));
  if (isLabeled()) {
    buf.append(indstr).append("String_Node_Str").append(this.id).append("String_Node_Str").append(new_line_separator);
    tracer.incrementSourceLine();
  }
  buf.append(indstr).append("String_Node_Str").append(new_line_separator);
  tracer.incrementSourceLine();
  buf.append(ExprProcessor.jmpWrapper(first,indent + 1,true,tracer));
  buf.append(indstr).append("String_Node_Str");
  for (int i=1; i < stats.size(); i++) {
    List<String> exception_types=exctstrings.get(i - 1);
    buf.append("String_Node_Str");
    if (exception_types.size() > 1) {
      for (int exc_index=1; exc_index < exception_types.size(); ++exc_index) {
        VarType exc_type=new VarType(CodeConstants.TYPE_OBJECT,0,exception_types.get(exc_index));
        String exc_type_name=ExprProcessor.getCastTypeName(exc_type);
        buf.append(exc_type_name).append("String_Node_Str");
      }
    }
    buf.append(vars.get(i - 1).toJava(indent,tracer));
    buf.append("String_Node_Str").append(new_line_separator);
    tracer.incrementSourceLine();
    buf.append(ExprProcessor.jmpWrapper(stats.get(i),indent + 1,true,tracer)).append(indstr).append("String_Node_Str");
    tracer.incrementSourceLine();
  }
  buf.append(new_line_separator);

}

Fixed version (ground truth):
public String toJava(int indent,BytecodeMappingTracer tracer){
  String indstr=InterpreterUtil.getIndentString(indent);
  StringBuilder buf=new StringBuilder();
  String new_line_separator=DecompilerContext.getNewLineSeparator();
  buf.append(ExprProcessor.listToJava(varDefinitions,indent,tracer));
  if (isLabeled()) {
    buf.append(indstr).append("String_Node_Str").append(this.id).append("String_Node_Str").append(new_line_separator);
    tracer.incrementCurrentSourceLine();
  }
  buf.append(indstr).append("String_Node_Str").append(new_line_separator);
  tracer.incrementCurrentSourceLine();
  buf.append(ExprProcessor.jmpWrapper(first,indent + 1,true,tracer));
  buf.append(indstr).append("String_Node_Str");
  for (int i=1; i < stats.size(); i++) {
    List<String> exception_types=exctstrings.get(i - 1);
    buf.append("String_Node_Str");
    if (exception_types.size() > 1) {
      for (int exc_index=1; exc_index < exception_types.size(); ++exc_index) {
        VarType exc_type=new VarType(CodeConstants.TYPE_OBJECT,0,exception_types.get(exc_index));
        String exc_type_name=ExprProcessor.getCastTypeName(exc_type);
        buf.append(exc_type_name).append("String_Node_Str");
      }
    }
    buf.append(vars.get(i - 1).toJava(indent,tracer));
    buf.append("String_Node_Str").append(new_line_separator);
    tracer.incrementCurrentSourceLine();
    buf.append(ExprProcessor.jmpWrapper(stats.get(i),indent + 1,true,tracer)).append(indstr).append("String_Node_Str");
