Dennis Balkir created OFBIZ-9630:
------------------------------------

             Summary: [FB] Package org.apache.ofbiz.common.login
                 Key: OFBIZ-9630
                 URL: https://issues.apache.org/jira/browse/OFBIZ-9630
             Project: OFBiz
          Issue Type: Sub-task
          Components: framework
    Affects Versions: Trunk
            Reporter: Dennis Balkir
            Priority: Minor


- LoginServices.java:118, DM_CONVERT_CASE
Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.common.login.LoginServices.userLogin(DispatchContext,
Map)

A String is being converted to upper or lowercase, using the platform's default encoding.
This may result in improper conversions when used with international characters. Use the

String.toUpperCase( Locale l )
String.toLowerCase( Locale l )
versions instead.

- LoginServices.java:161, DLS_DEAD_LOCAL_STORE
DLS: Dead store to loginDisableMinutes in org.apache.ofbiz.common.login.LoginServices.userLogin(DispatchContext,
Map)

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.

- LoginServices.java:569, DLS_DEAD_LOCAL_STORE
DLS: Dead store to resultMap in org.apache.ofbiz.common.login.LoginServices.createUserLogin(DispatchContext,
Map)

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.

- LoginServices.java:661, NP_LOAD_OF_KNOWN_NULL_VALUE
NP: Load of known null value in org.apache.ofbiz.common.login.LoginServices.updatePassword(DispatchContext,
Map)

The variable referenced at this point is known to be null due to an earlier check against
null. Although this is valid, it might be a mistake (perhaps you intended to refer to a different
variable, or perhaps the earlier check to see if the variable is null should have been a check
to see if it was non-null).

- LoginServices.java:671, DM_CONVERT_CASE
Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.common.login.LoginServices.updatePassword(DispatchContext,
Map)

A String is being converted to upper or lowercase, using the platform's default encoding.
This may result in improper conversions when used with international characters. Use the

String.toUpperCase( Locale l )
String.toLowerCase( Locale l )
versions instead.

- LoginServices.java:733, DM_CONVERT_CASE
Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.common.login.LoginServices.updateUserLoginId(DispatchContext,
Map)

A String is being converted to upper or lowercase, using the platform's default encoding.
This may result in improper conversions when used with international characters. Use the

String.toUpperCase( Locale l )
String.toLowerCase( Locale l )
versions instead.

- LoginServices.java:906, RCN_REDUNDANT_NULLCHECK_WOULD_HAVE_BEEN_A_NPE
RCN: Nullcheck of userLogin at line 915 of value previously dereferenced in org.apache.ofbiz.common.login.LoginServices.checkNewPassword(GenericValue,
String, String, String, String, List, boolean, Locale)

A value is checked here to see whether it is null, but this value can't be null because it
was previously dereferenced and if it were null a null pointer exception would have occurred
at the earlier dereference. Essentially, this code and the previous dereference disagree as
to whether this value is allowed to be null. Either the check is redundant or the previous
dereference is erroneous.

- LoginServices.java:915, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
RCN: Redundant nullcheck of currentPassword, which is known to be non-null in org.apache.ofbiz.common.login.LoginServices.checkNewPassword(GenericValue,
String, String, String, String, List, boolean, Locale)

This method contains a redundant check of a known non-null value against the constant null.

- LoginServices.java:988, DLS_DEAD_LOCAL_STORE
DLS: Dead store to messageMap in org.apache.ofbiz.common.login.LoginServices.checkNewPassword(GenericValue,
String, String, String, String, List, boolean, Locale)

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.

- LoginServices.java:1002, DM_CONVERT_CASE
Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.common.login.LoginServices.checkNewPassword(GenericValue,
String, String, String, String, List, boolean, Locale)

A String is being converted to upper or lowercase, using the platform's default encoding.
This may result in improper conversions when used with international characters. Use the

String.toUpperCase( Locale l )
String.toLowerCase( Locale l )
versions instead.
