Bug ID: 57433
Summary: Double-check locking in ExpressionEvaluatorManager
Product: Taglibs
Version: 1.2.1
Hardware: All
OS: All
Status: NEW
Severity: minor
Priority: P2
Component: Standard Taglib
Assignee: dev@tomcat.apache.org
Reporter: jboy...@apache.org
http://svn.apache.org/viewvc/tomcat/taglibs/standard/tags/taglibs-standard-1.2.1/jstlel/src/main/java/org/apache/taglibs/standard/lang/support/ExpressionEvaluatorManager.java?view=markup#l103
The default implementation, org.apache.taglibs.standard.lang.jstl.Evaluator,
does not have any instance fields so we may not see issues in the wild. The
taglibs code specifies a constant value for the name so it will always use that
implementation. However, other implementations stored in the cache may not be
safe.
