Examples of com.sun.messaging.jmq.util.PHashMapLoadException

com.sun.messaging.jmq.util.PHashMapLoadException
This class provides information about problems and/or data corruptions encountered when loading the a VRecord from the backing file. If the key and/or the value of the hash map entry is loaded successfully, it can be retrieved by calling getKey() and/or getValue respectively. The throwable caught while deserializing the key can be retrieved by calling getKeyCause(). Similarly, the throwable caught while deserializing the value can be retrieved by calling getValueCause(). Other exception caught while parsing the record, if any, can be retrieved by getCause. getNextException() returns the next chained exception for other loading problems or null if there's no more chained exception.
