[TECNICAL SUPPORT] LPS-32363 Omiting cache_bitmask field when serializing class which extends HashMap

Hi Zsigmond,

This is a JRockit issue vs XStream when we have a class which extends HashMap. The JRockit implementation has a private int cache_bitmask; field which is serialized into the XML file of a the page template during LAR export. This can cause error when importing into another instance of Liferay running on Oracle/Sun/Apple JVM.

Vilmos
