Description Greg Wilkins CLA 2010-06-04 19:33:54 EDT 
See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4513622

thus it may be better to wrap calls to substring in a call to new String(), so that short strings do not hold the larger strings in memory.
Comment 1 Simone Bordet CLA 2013-02-13 09:40:15 EST 
JDK bug #4513622 has been fixed in JDK 7u6, as reported in the JDK bug report.
No longer an issue.
