Subject [jira] [Updated] (OFBIZ-9627) [FB] Package org.apache.ofbiz.common.authentication
Date Fri, 25 Aug 2017 11:27:00 GMT

     [ https://issues.apache.org/jira/browse/OFBIZ-9627?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Dennis Balkir updated OFBIZ-9627:
    Attachment: OFBIZ-9627_org.apache.ofbiz.common.authentification_bugfixes.patch

- implementation of Serializable is not necessary
method compare:
- changed the comparison to {{Float.compare}}
- made a local parameter {{comp}} to save the value from {{Float.compare}} to use it
- instead of returning -1 or 1 it now returns the result of {{Float.compare}} put through
{{Math.signum}} (which then only returns -1 or 1)
- deleted unnecessary else

> - AuthenticationComparator.java:31, SE_COMPARATOR_SHOULD_BE_SERIALIZABLE
> Se: org.apache.ofbiz.common.authentication.AuthenticationComparator implements Comparator
but not Serializable
> This class implements the Comparator interface. You should consider whether or not it
should also implement the Serializable interface. If a comparator is used to construct an
ordered collection such as a TreeMap, then the TreeMap will be serializable only if the comparator
is also serializable. As most comparators have little or no state, making them serializable
is generally easy and good defensive programming.
> - AuthenticationComparator.java:70, CO_COMPARETO_INCORRECT_FLOATING
> compareTo()/compare() incorrectly handles float or double value
> This method compares double or float values using pattern like this: val1 > val2 ?
1 : val1 < val2 ? -1 : 0. This pattern works incorrectly for -0.0 and NaN values which
may result in incorrect sorting result or broken collection (if compared values are used as
keys). Consider using Double.compare or Float.compare static methods which handle all the
special cases correctly.
