How can I remove some opcodes from Java class file?

问题

Here are some code lines:

//   43: invokevirtual 10   test/main:a (I)test/sub1;
//   46: pop
//   47: goto +4 -> 51
//   50: athrow
//   51: aload_2

This is the byte code of a sample Java class file.

I want to remove the opcodes of lines 47, 50... from java class file.

How can I do this using ASM?
