What is Byte code enhancement

[MaheshS Kumbhar]

I read somewhere on blogs that Hibernate uses bytecode enhancement for its operation. But I didn't find any information that I could digest for what exactly is bytecode enhancement.
Can anyone please tell me what it is?

It's a technique used by many frameworks/libraries (Hibernate, Spring AOP etc...) to manipulate the .class files at runtime to various needs such as to add some framework specific defaults etc...

I'd suggest you read some articles about the subject to get an idea like this(and other related parts).
