    public class StringCharArrayAccessor
    extends java.lang.Object

Provides optimized access to java.lang.String internals - Optimized way of creating java.lang.String by reusing a char[] buffer - Optimized way of writing String to java.io.Writer java.lang.String creation reusing a char[] buffer requires Java 1.5+ System property "stringchararrayaccessor.disabled" disables this hack. -Dstringchararrayaccessor.disabled=true Read JSR-133, "9.1.1 Post-Construction Modification of Final Fields" http://www.cs.umd.edu/~pugh/java/memoryModel/jsr133.pdf
