DESCRIPTION
After setting the properties below in the JVM arguments, page names with the ampersand sign (&) will get truncated.

The system properties:
javax.xml.stream.XMLInputFactory=com.sun.xml.internal.stream.XMLInputFactoryImpl
javax.xml.stream.XMLOutputFactory=com.sun.xml.internal.stream.XMLOutputFactoryImpl

STEPS TO REPRODUCE

1. Get a new bundle of Liferay 6.1.30 (tomcat is fine)
2. Add these lines to the JVM arguments in tomcat/bin/setenv.sh:
   • -Djavax.xml.stream.XMLInputFactory=com.sun.xml.internal.stream.XMLInputFactoryImpl
   • -Djavax.xml.stream.XMLOutputFactory=com.sun.xml.internal.stream.XMLOutputFactoryImpl
3. Startup Liferay
4. Add a new page
5. Add a translation to the page with an ampersand in the name: 'test&test'
6. Save the page

Notes
Per Eric Chin,

See here for my fix: https://gist.github.com/ericchin/ecf0046386cef4e62b76#file-localizationimpl-java-L22-L33

The fix from LPS-14852 was made to com.liferay.portal.util.LocalizationImpl#getLocalization. I would like to have the same fix for com.liferay.portal.util.LocalizationImpl#_copyNonExempt
