Patch for the DOMElementWriter class
Our Unit Test contains keeps failing with java.lang.OutOfMemory exception when
the test results are written into the XML/text file.
First problem was solved by applying the patch from patch from the
https://issues.apache.org/bugzilla/show_bug.cgi?id=45536.
But it still does not helped, and the exception is still thrown:
[epos junit] Exception in thread "main" java.lang.OutOfMemoryError: Java heap

After a short investigation I have found, that the problem lies in the
conversion of the DOM representation into the XML/Text file, caused by multiple
allocation of the memory for storing of the string data of the CDATA element.
I have skipped the copy of the CDATA into the memory, the data will be written
directly into the output stream, instead (see the attached patch).
