```
public VerificationResult do_verify()
```
    Pass 3a is the verification of static constraints of JVM code (such as legal targets of branch instructions). This is the part of pass 3 where you do not need data flow analysis. JustIce also delays the checks for a correct exception table of a Code attribute and correct line number entries in a LineNumberTable attribute of a Code attribute (which conceptually belong to pass 2) to this pass. Also, most of the check for valid local variable entries in a LocalVariableTable attribute of a Code attribute is delayed until this pass. All these checks need access to the code array of the Code attribute.
