> -------------------------------------------------------------------------------

> Key: OPENJPA-2882
> URL: https://issues.apache.org/jira/browse/OPENJPA-2882
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.2.3
> Reporter: Will Dazey
> Priority: Minor

> Exception:
> {code:java}
> java.lang.IllegalArgumentException: argument type mismatch

> Caused by: java.lang.IllegalArgumentException: Error while setting value
> 34567 of class java.lang.String by setter method public
> org.apache.openjpa.persistence.jdbc.JDBCFetchPlan
> org.apache.openjpa.persistence.jdbc.JDBCFetchPlanImpl.setLockTimeout(int) of

> org.apache.openjpa.enhance.Reflection.wrapReflectionException(Reflection.java:347)
> at org.apache.openjpa.enhance.Reflection.set(Reflection.java:779)
> {code}
> Fairly easy to reproduce:
> Test:
> {code:java}
> Map<String, Object> properties = new HashMap<String, Object>();
> properties.put("javax.persistence.lock.timeout", "34567");
> EntityManager em = emf.createEntityManager(properties);
> {code}
> Whats happening:
> `org.apache.openjpa.enhance.Reflection.findSetter(org.apache.openjpa.persistence.jdbc.JDBCFetchPlanImpl,
> "LockTimeout")` is returning a setter
> ```
> public org.apache.openjpa.persistence.jdbc.JDBCFetchPlan
> org.apache.openjpa.persistence.jdbc.JDBCFetchPlanImpl.setLockTimeout(int)
> ```
> However,
> `org.apache.openjpa.persistence.EntityManagerImpl.convertUserValue("javax.persistence.lock.timeout",
> "34567", int)` is failing to accurately convert the value from String ->
> int. You might think "oh, well then just pass in (int) 34567 and not (String)
> 34567". However, this isnt always possible. The actual usecase that exposed
> this issue is using deployment descriptors to pass the persistence context
> property:
> {code:java}
> <persistence-context-ref>
> <persistence-property>
> <name>javax.persistence.lock.timeout</name>
> <value>34567</value>
> </persistence-property>
> </persistence-context-ref>
> {code}
> also, this reflection exception doesnt occur if the same property is passed
> to createEntityManagerFactory(Map)! Inconsistent behavior and a runtime
> reflection exception that shouldn't occur.
