java bytecode exception catch block's boundary

I got a class which generated by dex2jar, the bytecode like this

  public boolean a(com.google.android.exoplayer2.metadata.Metadata);
    descriptor: (Lcom/google/android/exoplayer2/metadata/Metadata;)Z
    flags: (0x0001) ACC_PUBLIC

      Exception table:
         from    to  target type
            75   100   136   Class java/lang/NumberFormatException
           109   120   136   Class java/lang/NumberFormatException

in my opinion: the exception try block’s last instruction’s next must be the catch block’s start instruction.

but this example broke my mind, and the logical is correct!

try block: from 75 to 120, catch block: 136

I want to know is there any other java compiler or non-java compiler optimize instructions like this example.
