CWE-574: EJB Bad Practices: Use of Synchronization Primitives

MITRE CWE weakness

Description

The product violates the Enterprise JavaBeans (EJB) specification by using thread synchronization primitives.

The Enterprise JavaBeans specification requires that every bean provider follow a set of programming guidelines designed to ensure that the bean will be portable and behave consistently in any EJB container. In this case, the product violates the following EJB guideline: "An enterprise bean must not use thread synchronization primitives to synchronize execution of multiple instances." The specification justifies this requirement in the following way: "This rule is required to ensure consistent runtime semantics because while some EJB containers may use a single JVM to execute all enterprise bean's instances, others may distribute the instances across multiple JVMs."

Common consequences

• Other: Quality Degradation

Mitigations

Implementation — Do not use Synchronization Primitives when writing EJBs.
