> - ComponentContainer.java:140, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
> RCN: Redundant nullcheck of componentLoadFile, which is known to be non-null in org.apache.ofbiz.base.container.ComponentContainer.loadComponentDirectory(String)
> This method contains a redundant check of a known non-null value against the constant
null.
> - ComponentContainer.java:165, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
> RCN: Redundant nullcheck of componentsToLoad, which is known to be non-null in org.apache.ofbiz.base.container.ComponentContainer.loadComponentsInDirectoryUsingLoadFile(File,
File)
> This method contains a redundant check of a known non-null value against the constant
null.
> - ComponentContainer.java:187, NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE
> NP: Possible null pointer dereference in org.apache.ofbiz.base.container.ComponentContainer.loadComponentsInDirectory(File)
due to return value of called method
> The return value from a method is dereferenced without a null check, and the return value
of that method is one that should generally be checked for null. This may lead to a NullPointerException
when the code is executed.
> - ContainerConfig.java:102, DLS_DEAD_LOCAL_STORE
> DLS: Dead store to num in org.apache.ofbiz.base.container.ContainerConfig.getPropertyValue(ContainerConfig$Configuration,
String, int)
> This instruction assigns a value to a local variable, but the value is not read or used
in any subsequent instruction. Often, this indicates an error, because the value computed
is never used.
> Note that Sun's javac compiler often generates dead stores for final local variables.
Because FindBugs is a bytecode-based tool, there is no easy way to eliminate these false positives.
> - ContainerConfig.java:135, DLS_DEAD_LOCAL_STORE
> DLS: Dead store to num in org.apache.ofbiz.base.container.ContainerConfig.getPropertyValue(ContainerConfig$Configuration$Property,
String, int)
> 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.
