For each assert in my Java code, SQLJ generates an error indicating (error unpaired key).
It looks like SQLJ does not support the word "assert", however it is part of the specification of Java 1.4. In the other hand, it supports other more recent features such as generics, annotations and enhanced for, that are part of the Java 1.5 specification.

What can I do?
