Build the code with ASM 4 and Guava 12 as follows:

$ javac -cp $HOME/.m2/repository/org/ow2/asm/asm-all/4.0/asm-all-4.0.jar:$HOME/.m2/repository/com/google/guava/guava/12.0/guava-12.0.jar:. FibGeneratedAsm.java

Code can be run with:

$ ~/jdk-back/1.8.0-mlvm-2012_08_01_10_07/Contents/Home/bin/java -cp $HOME/.m2/repository/org/o/asm/asm-all/4.0/asm-all-4.0.jar:$HOME/.m2/repository/com/google/guava/guava/12.0/guava-12.0.jar:. FibGeneratedAsm
