> - UomWorker.java:70, PZLA_PREFER_ZERO_LENGTH_ARRAYS
> PZLA: Should org.apache.ofbiz.common.uom.UomWorker.uomTimeToCalTime(String)
> return a zero length array rather than null?
> It is often a better design to return a length zero array rather than a null
> reference to indicate that there are no results (i.e., an empty list of
> results). This way, no explicit check for null is needed by clients of the
> method.
> On the other hand, using null to indicate "there is no answer to this
> question" is probably appropriate. For example, File.listFiles() returns an
> empty list if given a directory containing no files, and returns null if the
> file is not a directory.
> - UomWorker.java:107, DLS_DEAD_LOCAL_STORE
> DLS: Dead store to svcOutMap in
> org.apache.ofbiz.common.uom.UomWorker.convertUom(BigDecimal, String, String,
> LocalDispatcher)
> This instruction assigns a value to a local variable, but the value is not
> read or used in any subsequent instruction. Often, this indicates an error,
> because the value computed is never used.
> Note that Sun's javac compiler often generates dead stores for final local
> variables. Because FindBugs is a bytecode-based tool, there is no easy way to
> eliminate these false positives.
