Yes, ideally. But query fetch plan's lock timeout is currently interpreted as

FetchPlan/FetchConfiguration currently is not holding two separate timeout

May be OPENJPA-878 should consider such a change.

>> + *
>> + * The hint keys from following sources are collected and handled:
>> + *
>> + * 1. {...@link org.apache.openjpa.kernel.QueryHints} interface declares
>> hint keys
>> + * as public static final fields. These fields are collected by
>> reflection.
>> + * The values are handled by invoking methods on the owning {...@link
>> QueryImpl}
>> + *
>> + * 2. Some hint keys are collected from bean-style property names of
>> {...@link
>> + * JDBCFetchPlan} by {...@link
>> Reflection#getBeanStylePropertyNames(Class)
>> + * reflection} and prefixed with <code>openjpa.FetchPlan</code>.
>> + * Their values are used to set the corresponding property of {...@link
>> + * FetchPlan} via {...@link #hintToSetter(FetchPlan, String, Object)
>> reflection}
>> + *
>> + * 3. Currently defined <code>javax.persistence.*</code> hint keys have
>> + * a equivalent counterpart to one of these FetchPlan keys.
>> + * The JPA keys are mapped to equivalent FetchPlan hint keys.
>> + *
>> + * 4. Some keys directly invoke setters or add listeners to the owning
>> + * {...@link QueryImpl}. These hint keys are statically declared in
>> + * this receiver itself.
>> + *
>> + * 5. ProductDerivation may introduce their own query hint keys via
>> {...@link
>> + * ProductDerivation#getSupportedQueryHints()}. Their values are set
>> in the
>> + * {...@link FetchConfiguration#setHint(String, Object)}
>> + *
>> + * A hint key is classified into one of the following three categories:
>> + *
>> + * 1. Supported: A key is known to this receiver as collected from
>> different
>> + * parts of the system. The value of a supported key is recorded and
>> + * available via {...@link #getHints()} method.
>> + * 2. Recognized: A key is not known to this receiver but has a prefix
>> which
>> + * is known to this receiver. The value of a recognized key is not
>> recorded
>> + * but its value is available via {...@link
>> FetchConfiguration#getHint(String)}
>> + * 3. Unrecognized: A key is neither supported nor recognized. The
>> value of a
>> + * unrecognized key is neither recorded nor set anywhere.
>> + *
>> + * If an incompatible value is supplied for a supported key, a
>> non-fatal
>> + * {...@link ArgumentException} is raised.
