Minor Description
CatalogAltUrlSeoTransform.java:169, DM_STRING_TOSTRING
- Dm: org.apache.ofbiz.product.category.ftl.CatalogAltUrlSeoTransform$1.close() invokes toString() method on a String
Calling String.toString() is just a redundant operation. Just use the String.
CatalogUrlSeoTransform.java:531, WMI_WRONG_MAP_ITERATOR
- WMI: org.apache.ofbiz.product.category.ftl.CatalogUrlSeoTransform.forwardUri(HttpServletRequest, HttpServletResponse, Delegator, String) makes inefficient use of keySet iterator instead of entrySet iterator
This method accesses the value of a Map entry, using a key that was retrieved from a keySet iterator. It is more efficient to use an iterator on the entrySet of the map, to avoid the Map.get(key) lookup.
CatalogUrlSeoTransform.java:642, WMI_WRONG_MAP_ITERATOR
- WMI: org.apache.ofbiz.product.category.ftl.CatalogUrlSeoTransform.forwardCategoryUri(HttpServletRequest, HttpServletResponse, Delegator, String) makes inefficient use of keySet iterator instead of entrySet iterator
This method accesses the value of a Map entry, using a key that was retrieved from a keySet iterator. It is more efficient to use an iterator on the entrySet of the map, to avoid the Map.get(key) lookup.
CatalogUrlSeoTransform.java:699, NP_LOAD_OF_KNOWN_NULL_VALUE
- NP: Load of known null value in org.apache.ofbiz.product.category.ftl.CatalogUrlSeoTransform.makeProductUrl(Delegator, ProductContentWrapper, String, String, String, String, String)
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).
CatalogUrlSeoTransform.java:707, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
- RCN: Redundant nullcheck of trail, which is known to be non-null in org.apache.ofbiz.product.category.ftl.CatalogUrlSeoTransform.makeProductUrl(Delegator, ProductContentWrapper, String, String, String, String, String)
This method contains a redundant check of a known non-null value against the constant null.
CatalogUrlSeoTransform.java:781, NP_LOAD_OF_KNOWN_NULL_VALUE
- NP: Load of known null value in org.apache.ofbiz.product.category.ftl.CatalogUrlSeoTransform.makeCategoryUrl(Delegator, CategoryContentWrapper, String, String, String, String, String, String, String, String)
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).
CatalogUrlSeoTransform.java:782, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE

This method contains a redundant check of a known non-null value against the constant null.
OfbizCatalogAltUrlTransform.java:143, DM_STRING_TOSTRING
- Dm: org.apache.ofbiz.product.category.ftl.OfbizCatalogAltUrlTransform$1.close() invokes toString() method on a String
Calling String.toString() is just a redundant operation. Just use the String.
SeoTransform.java:71, SIC_INNER_SHOULD_BE_STATIC_ANON
- SIC: The class org.apache.ofbiz.product.category.ftl.SeoTransform$1 could be refactored into a named static inner class
This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary. If possible, the class should be made into a static inner class. Since anonymous inner classes cannot be marked as static, doing this will require refactoring the inner class so that it is a named inner class.
SeoTransform.java:121, REC_CATCH_EXCEPTION
- REC: Exception is caught when Exception is not thrown in org.apache.ofbiz.product.category.ftl.SeoTransform$1.close()
This method uses a try-catch block that catches Exception objects, but Exception is not thrown within the try block, and RuntimeException is not explicitly caught. It is a common bug pattern to say try
{ ... } catch (Exception e) { something } as a shorthand for catching a number of types of exception each of whose catch blocks is identical, but this construct also accidentally catches RuntimeException as well, masking potential bugs.A better approach is to either explicitly catch the specific exceptions that are thrown, or to explicitly catch RuntimeException exception, rethrow it, and then catch all non-Runtime Exceptions, as shown below:
try { ... } catch (RuntimeException e) { throw e; } catch (Exception e) { ... deal with all non-runtime exceptions ... }
