Possible null pointer dereference
There is a branch of statement that, if executed, guarantees that
a null value will be dereferenced, which
would generate a NullPointerException when the code is executed.
Of course, the problem might be that the branch or statement is infeasible and that
the null pointer exception can't ever be executed; deciding that is beyond the ability of SpotBugs.
]]>
Unwritten field
This field is never written. All reads of it will return the default
value. Check for errors (should it have been initialized?), or remove it if it is useless.
]]>
Read of unwritten field
The program is dereferencing a field that does not seem to ever have a non-null value written to it.
Unless the field is initialized via some mechanism not seen by the analysis,
dereferencing this value will generate a null pointer exception.
]]>
Should be a 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 static.
]]>
Bad comparison of nonnegative value with negative constant or zero
This code compares a value that is guaranteed to be non-negative with a negative constant or zero.
