An identifier declared in an inner scope should not hide an identifier in an outer scope.

DCL01-C

V5002

OWASP. An empty exception handler. Silent suppression of exceptions can hide the presence of bugs in source code during testing.

ERR56-CPP

V5003

OWASP. The object was created but it is not being used. The 'throw' keyword could be missing.

MSC13-C

V5004

OWASP. Consider inspecting the expression. Bit shifting of the 32-bit value with a subsequent expansion to the 64-bit type.

INT00-C

V5005

OWASP. A value is being subtracted from the unsigned variable. This can result in an overflow. In such a case, the comparison operation can potentially behave unexpectedly.

INT30-C

V5006

OWASP. More than N bits are required to store the value, but the expression evaluates to the T type which can only hold K bits.

INT02-C

V5010

OWASP. The variable is incremented in the loop. Undefined behavior will occur in case of signed integer overflow.

INT32-C

V5011

OWASP. Possible overflow. Consider casting operands, not the result.

INT30-C

Error Description

Mapping

V5301

OWASP. An exception handling block does not contain any code.

ERR00-J

V5304

OWASP. Unsafe double-checked locking.

LCK10-J

V6002

The switch statement does not cover all values of the enum.

MSC57-J

V6003

The use of 'if (A) {...} else if (A) {...}' pattern was detected. There is a probability of logical error presence.

MSC57-J

V6005

The 'x' variable is assigned to itself.

MSC56-J

V6007

Expression is always true/false.

MSC57-J

V6008

Potential null dereference.

EXP01-J

V6010

The return value of function 'Foo' is required to be utilized.

EXP00-J

V6011

The expression contains a suspicious mix of integer and real types.

NUM13-J

V6013

Comparison of arrays, strings, collections by reference. Possibly an equality comparison was intended.

EXP03-J

V6018

Constant expression in switch statement.

MSC57-J

V6020

Division or mod division by zero.

NUM02-J

V6021

The value is assigned to the 'x' variable but is not used.

MSC56-J

V6022

Parameter is not used inside method's body.

MSC56-J

V6026

This value is already assigned to the 'b' variable.

MSC56-J

V6031

The variable 'X' is being used for this loop and for the outer loop.

MSC57-J

V6034

Shift by N bits is inconsistent with the size of type.

NUM14-J

V6037

An unconditional 'break/continue/return/goto' within a loop.

MSC57-J

V6038

Comparison with 'double.NaN' is meaningless. Use 'double.isNaN()' method instead.

NUM07-J

V6039

There are two 'if' statements with identical conditional expressions. The first 'if' statement contains method return. This means that the second 'if' statement is senseless.

MSC56-J

V6041

Suspicious assignment inside the conditional expression of 'if/while/do...while' statement.

EXP51-J

V6044

Postfix increment/decrement is senseless because this variable is overwritten.

EXP05-J

V6049

Classes that define 'equals' method must also define 'hashCode' method.

MET09-J

V6050

Class initialization cycle is present.

DCL00-J

V6051

Use of jump statements in 'finally' block can lead to the loss of unhandled exceptions.

ERR04-J

V6052

Calling an overridden method in parent-class constructor may lead to use of uninitialized data.

MET05-J

V6053

Collection is modified while iteration is in progress. ConcurrentModificationException may occur.

MSC06-J

V6054

Classes should not be compared by their name.

OBJ09-J

V6055

Expression inside assert statement can change object's state.

EXP06-J

V6057

Consider inspecting this expression. The expression is excessive or contains a misprint.

MSC57-J

V6061

The used constant value is represented by an octal form.

DCL50-J

V6063

Odd semicolon ';' after 'if/for/while' operator.

MSC51-J

V6064

Suspicious invocation of Thread.run().

THI00-J

V6066

Passing objects of incompatible types to the method of collection.

EXP04-J

V6068

Suspicious use of BigDecimal class.

NUM10-J

V6070

Unsafe synchronization on an object.

LCK01-J

V6073

It is not recommended to return null or throw exceptions from 'toString' / 'clone' methods.

EXP01-J

V6074

Non-atomic modification of volatile variable.

VNA02-J

V6075

The signature of method 'X' does not conform to serialization requirements.

SER01-J

V6077

A suspicious label is present inside a switch(). It is possible that these are misprints and 'default:' label should be used instead.

MSC57-J

V6082

Unsafe double-checked locking.

LCK10-J

V6089

It's possible that the line was commented out improperly, thus altering the program's operation logics.

EXP52-J

V6093

Automatic unboxing of a variable may cause NullPointerException.

EXP01-J

V6095

Thread.sleep() inside synchronized block/method may cause decreased performance.

LCK09-J

V6097

Lowercase 'L' at the end of a long literal can be mistaken for '1'.

DCL50-J

V6101

compareTo()-like methods can return not only the values -1, 0 and 1, but any values.
