Welcome to JavaRanch.

JVMs generally are backwards-compatible, meaning that whatever runs on Java 1.4 should run on Java 5. Have you encountered any problems?

Hi
I do agree the previous comment . But there may be impact if your doing build process conituously .

Two place where I encountered problems

1) Enum - since from 1.5 Enum is keyword , it may through error if it is used as variable name.
2) Generics - The compiler may give warning about type safty .

Though these can be avoided by using proper parameters to JVM , I though of listing out ..Request your comments..
