This problem occurs on a licensee's JSP application.
Tomcat generates _jspService() method and sometimes it is very long,
and uses oldjavac (sun.tools.javac.Main) to compile it.

Although this problem does not occur on server VM on JRE 1.3.x and
any VM on JRE 1.4.0-beta3, a licensee wants a fix in JRE 1.3.x.
 
Additionally, even when it runs, this long method takes long time to finish
without increasing NewSize by unsupported -XX:NewSize option.
Please try with -verbose:gc option. GC occurs many times and takes long time
for each time.
