This is a test case I wrote using Junit to show the bug. It needs a breakpoint to show
the threading problem.
Race condition when adding an object to PojoCache while another
thread may read that object
-------------------------------------------------------------------------------------------
Key: JBCACHE-1078
URL: http://jira.jboss.com/jira/browse/JBCACHE-1078
Project: JBoss Cache
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: PojoCache
Affects Versions: 2.0.0.BETA1, 2.0.0.BETA2, 2.0.0.CR1
Reporter: Vincent Marquez
Assigned To: Jason T. Greene
Attachments: ThreadTest.java
When adding an object to PojoCache, AdvisedPojoHandler attaches a CachedFieldInterceptor
to the advised object being added.(line 125) It does this before it adds the object to
the actual Cache. If another thread reads this object in between the time the
CachedFieldInterceptor is added and the object is inserted into the cache, (line 178) an
exception will be thrown in the Reading
thread:org.jboss.cache.pojo.PojoCacheAlreadyDetachedException: pojo: class
org.jboss.cache.pojo.test.Person has possibly been detached remotely.
