Suppress issues found by FindBugs: EI_EXPOSE_REP and EI_EXPOSE_REP2
http://findbugs.sourceforge.net/bugDescriptions.html#EI_EXPOSE_REP
http://findbugs.sourceforge.net/bugDescriptions.html#EI_EXPOSE_REP2
A proper fix for EI_EXPOSE_REP would require eventually to return a copy of an
internal object.
A proper fix for EI_EXPOSE_REP2 would require eventually to store a copy of the
provided object-argument.
However, the performance implication of creating the extra copies is not clear,
hence for the time being all those issues are suppressed by using the following
statements:
@SuppressFBWarnings(value = "EI_EXPOSE_REP",
justification = "TODO: Return a copy of the object?")
@SuppressFBWarnings(value = "EI_EXPOSE_REP2",
justification = "TODO: Store a copy of the object?")
Those suppressed warnings should be re-evaluated and addressed on case-by-case, e.g.
create object copies as appropriate.
