我刚刚升级到datanucleus-core 3.2.10（3.3.5）并且突然对我的一个对象的简单查询不起作用，我似乎找不到原因。
我正在使用以下DN lib datanucleus-core 3.2.10 datanucleus-api-jdo 3.2.6 datanucleus-rdbms 3.2.9 datanucleus-jdo-query 3.0.2 datanucleus-googlecollections 3.2.2
我正在运行查询：
Query q = pm.newQuery(User.class);
q.declarParameters("String myKey");
q.setFilter("this.key == myKey");
List<User> results = (List<User>) q.execute("4762");
User.class的JDO文件
<jdo>
<package name="org.sly.main.shared.data.user">
<class name="User" detachable="true">
<inheritance strategy="new-table">
<discriminator strategy="value-map" value="USER_MAIN" />
</inheritance>
<version strategy="version-number" />
<unique name="unique_username">
<field name="username" />
</unique>
<field name="key" persistence-modifier="persistent"
value-strategy="increment" primary-key="true">
<column length="32" jdbc-type="VARCHAR" />
</field>
<field name="name" persistence-modifier="persistent" />
<field name="username" persistence-modifier="persistent" />
<field name="groups" persistence-modifier="persistent" default-fetch-group="true">
<join />
</field>
</class>
</package>
UserGroup.class的JDO文件
<jdo>
<package name="org.sly.main.shared.data.user.group">
<class name="UserGroup" detachable="true">
<version strategy="version-number" />
<field name="key" persistence-modifier="persistent"
value-strategy="increment" primary-key="true">
<column length="32" jdbc-type="VARCHAR" />
</field>
<field name="name" persistence-modifier="persistent" />
<field name="systemReference" persistence-modifier="persistent" />
<field name="exclusionGroupId" persistence-modifier="persistent" />
<field name="displayName" persistence-modifier="persistent" />
</class>
</package>
