------------------------------
Summary: Double checked locking in PolicyEngineImpl.java
Key: CXF-7184
URL: https://issues.apache.org/jira/browse/CXF-7184
Project: CXF
Issue Type: Bug
Components: JAX-WS Runtime
Affects Versions: 3.1.8, 3.2.0, 3.1.10, 3.0.13
Reporter: Wil Evers
Method createEndpointPolicyInfo() in
rt/ws/policy/src/main/java/org/apache/cxf/ws/policy/PolicyEngineImpl.java
contains a classic instance of the double checked locking pattern, which may
cause an object to become visible to a different thread in a partially
initialized state.
Please see The "Double-Checked Locking is Broken" Declaration
(https://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html) to
understand why this happens. A quick Google search should return several
possible solutions.
