A try/finally with nothing in the finally results in additional byte codes being generated.

Here's the test case:
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.File;
import javax.swing.*;
import javax.swing.filechooser.*;

public class Test {
    public static void main(String[] args) {
        JComponent x = new JComponent() {
            public boolean isShowing() {
                return true;
            }
            public boolean isOpaque() {
                return true;
            }
        };
        // try {
        x.setSize(200, 200);
        x.paintImmediately(0, 0, 200, 200);
        System.out.println("DONE!");
        // } finally {}
    }
}

Here's the output from javap as is:
Compiled from "Test.java"
public class Test extends java.lang.Object{
public Test();
  Code:
   0:aload_0
   1:invokespecial#1; //Method java/lang/Object."<init>":()V
   4:return

public static void main(java.lang.String[]);
  Code:
   0:new#2; //class Test$1
   3:dup
   4:invokespecial#3; //Method Test$1."<init>":()V
   7:astore_1
   8:aload_1
   9:sipush200
   12:sipush200
   15:invokevirtual#4; //Method javax/swing/JComponent.setSize:(II)V
   18:aload_1
   19:iconst_0
   20:iconst_0
   21:sipush200
   24:sipush200
   27:invokevirtual#5; //Method javax/swing/JComponent.paintImmediately:(IIII)V
   30:getstatic#6; //Field java/lang/System.out:Ljava/io/PrintStream;
   33:ldc#7; //String DONE!
   35:invokevirtual#8; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
   38:return

}

And when you uncomment the try/finally here's the output:
Compiled from "Test.java"
public class Test extends java.lang.Object{
public Test();
  Code:
   0:aload_0
   1:invokespecial#1; //Method java/lang/Object."<init>":()V
   4:return

public static void main(java.lang.String[]);
  Code:
   0:new#2; //class Test$1
   3:dup
   4:invokespecial#3; //Method Test$1."<init>":()V
   7:astore_1
   8:aload_1
   9:sipush200
   12:sipush200
   15:invokevirtual#4; //Method javax/swing/JComponent.setSize:(II)V
   18:aload_1
   19:iconst_0
   20:iconst_0
   21:sipush200
   24:sipush200
   27:invokevirtual#5; //Method javax/swing/JComponent.paintImmediately:(IIII)V
   30:getstatic#6; //Field java/lang/System.out:Ljava/io/PrintStream;
   33:ldc#7; //String DONE!
   35:invokevirtual#8; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
   38:goto44
   41:astore_2
   42:aload_2
   43:athrow
   44:return
  Exception table:
   from to target type
     8 38 41 any
    41 42 41 any

}


I'm not sure if this intentional for debugging purposes, hence filing as an RFE.
