Question: what is wrong elf class elfclass32?
Answer: This was due to the possibility of the JVM being a 64-bit one, which was incapable of operating in the 32-bit mode. The resolution might therefore be to install a 32-bit version of JVM, and use the same. https://stackoverflow.com/questions/6172105/wrong-elf-class-elfclass32/6173613#6173613.
