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

V5301

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

ERR00-J

V5304

OWASP. Unsafe double-checked locking.

V6007

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.

Suspicious use of BigDecimal class.

NUM10-J

V6070

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

Automatic unboxing of a variable may cause NullPointerException.

EXP01-J

V6095

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

EXP00-J

V6108

Do not use real-type variables in 'for' loop counters.

NUM00-J

V6124

Converting an integer literal to the type with a smaller value range will result in overflow.
