Will Dazey updated OPENJPA-2882:
--------------------------------
Description:
Exception:
```
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
instance org.apache.openjpa.persistence.jdbc.JDBCFetchPlanImpl@28d133b9 by
reflection.
at
org.apache.openjpa.enhance.Reflection.wrapReflectionException(Reflection.java:347)
at org.apache.openjpa.enhance.Reflection.set(Reflection.java:779)
```
Fairly easy to reproduce:
Test:
```java
Map<String, Object> properties = new HashMap<String, Object>();
properties.put("javax.persistence.lock.timeout", "34567");
EntityManager em = emf.createEntityManager(properties);
```
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:
```xml
<persistence-context-ref>
<persistence-property>
<name>javax.persistence.lock.timeout</name>
<value>34567</value>
</persistence-property>
</persistence-context-ref>
```
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.
