----------------------------------
Summary: Synchronization on a string literal
Key: OWB-1154
URL: https://issues.apache.org/jira/browse/OWB-1154
Project: OpenWebBeans
Issue Type: Bug
Affects Versions: 1.7.0, 1.7.1
Reporter: Svetlin Zarev
Priority: Minor
String literals are constant and are automatically interned, and hence act as
global variables in the JVM. If someone tries to synchronize on the same string
literal, a deadlock might occur. More information on the issue of synchronizing
on strings:

The affected method is initSessionContext(Object startupObject):

The issue has been discovered as a result of static code analysis
