[樂意黎原創] glassfish里拋出Note: string:///XXX_jsp.java from uses unchecked or unsafe

glassfish里拋出以下毛病：

org.apache.jasper.JasperException: PWC6033: Unable to compile class for JSP

PWC6199: Generated servlet error:
string:///XXXX_jsp.java:169: constant string too long

PWC6199: Generated servlet error:
Note: string:///XXXX_jsp.java from  uses unchecked or unsafe operations.

折騰了好久，始終找不到緣由。
最后，經老大指導，并實際測試。終究發現緣由 
是由于glassfish里 把genStrAsCharArray 項設為 true 致使的。
解決辦法：

具體為：
把 $GLASSFISH_HOME/domains/domain1/config/default-web.xml 里的 
<param-name>genStrAsCharArray</param-name>
<param-value>true</param-value>

修改成：

<param-name>genStrAsCharArray</param-name>
<param-value>false</param-value>

genStrAsCharArray
false
If
 set to true, generates text strings as char arrays, which
 improves performance in some cases.
The default-web.xml file defines features such as filters and security constraints that apply to all web applications.  The parameter, development=true, (the default value for developer profile) enables changes made to JSPTM
