----------------------------------
Summary: MP Rest Client leaks async interceptors
Key: CXF-7992
URL: https://issues.apache.org/jira/browse/CXF-7992
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.3.1, 3.3.0
Reporter: Andy McCright
Assignee: Andy McCright
Every async method request on the MP Rest Client results in new
MPAsyncInvocationInterceptorPostAsyncImpl and
MPAsyncInvocationInterceptorRemoveAsyncImpl interceptors applied to the
ClientConfiguration associated with the proxy impl. This can quickly lead to
OOM conditions.
