The caveats are:

1. If your code is written for Java 1,7 you must have a Java 1.7+
runtime.  It might not be available for a given platform.

2. a given JVM might have a bug that stops some particular program
from working.

3. If you use JNI, you must have the appropriate native code for the
given platform.

4. Java does requires the programmer to handle the WORA stuff
explicitly for file names and line separators and encodings.  Simple
programs will work fine, but more complex ones must be aware.

If you look in a computer programmer's freezer you will find all 
kinds of containers, but none of them labeled.  They do the same thing 
creating files without labeling the encoding.  You are just supposed to 
know.  Ditto with the MIME type, the separator and comment delimiters and 
column names in CSV files.  Ditto with the endian convention.  Imagine how 
much more civilised life would have been if Martha Stewart were the first 
programmer.
