Enterprise Java Bean class static final fields test.
An enterprise Bean must not use read/write static fields. Using read-only
static fields is allowed. Therefore, it is recommended that all static
fields in the enterprise bean class be declared as final.
This rule is required to ensure consistent runtime semantics because while
some EJB Containers may use a single JVM to execute all enterprise bean's
instances, others may distribute the instances across multiple JVMs.

// hack to prevent compiler bug, don't want to process fields such as
// class$test$enforcer$hello$HelloHome, so if the field contains a "$"
// just skip it, otherwise process normally.
// if "$" does not occur as a substring, -1 is returned.
