RFR (JDK11/java.xml) 8201138: Defect in XMLEventReader.getElementText() may cause data to be skipped, duplicated or otherwise result in a ClassCastException

[Joe Wang]

Hi,

Please review a fix for a defect in XMLEventReader. The issue was that 
variable 'type' and 'data' were not set properly within the while statement.
