Jdk 1.5/1.6 GC log output analyze with GCCiewer. getting warning.

Question

Hi All,
I am trying to analyze gc.log (using jdk 1.5) file with GCViewer (www.tagtraum.com/gcviewer.html ).
It is taking file as "File format: Sun 1.4.x and displaying warning in some data rows like.
INFO [DataReaderFactory]: File format: Sun 1.4.x
INFO [DataReaderSun1_4_0]: Reading Sun 1.4.x/1.5.x format...
WARNUNG [DataReaderSun1_4_0]: Error parsing entry, java.lang.NumberFormatException: 80.493: [CMS-concurrent-mark-start]
WARNUNG [DataReaderSun1_4_0]: Error parsing entry, java.lang.NumberFormatException: For input string: "0.275/0.885 secs] [Times"
WARNUNG [DataReaderSun1_4_0]: Error parsing entry, java.lang.NumberFormatException: 81.378: [CMS-concurrent-preclean-start]
WARNUNG [DataReaderSun1_4_0]: Error parsing entry, java.lang.NumberFormatException: For input string: "0.022/0.023 secs] [Times"
WARNUNG [DataReaderSun1_4_0]: Error parsing entry, java.lang.NumberFormatException: 81.401: [CMS-concurrent-abortable-preclean-start]
When I have added (manually) below line in gc.log as first line. Then GCViewer has accepted this file as "File format: Sun 1.5.x"
1.095: [GC [1 CMS-initial-mark: 25798K(49152K)] 27626K(63936K), 0.0187882 secs] [Times: user=0.02 sys=0.00, real=0.02 secs]
INFO [DataReaderFactory]: File format: Sun 1.5.x
INFO [DataReaderSun1_4_0]: Reading Sun 1.4.x/1.5.x format...
WARNUNG [DataReaderSun1_5_0]: java.lang.NumberFormatException: 82.842: [Full GC 82.842: [CMS82.845: [CMS-concurrent-abortable-preclean: 0.414/1.443 secs] [Times: user=2.07 sys=0.11, real=1.44 secs] while parsing line: 82.842: [Full GC 82.842: [CMS82.845: [CMS-concurrent-abortable-preclean: 0.414/1.443 secs] [Times: user=2.07 sys=0.11, real=1.44 secs]
java.lang.NumberFormatException: 82.842: [Full GC 82.842: [CMS82.845: [CMS-concurrent-abortable-preclean: 0.414/1.443 secs] [Times: user=2.07 sys=0.11, real=1.44 secs]
Now as during analysis, it is not taking care of WARNING lines, means results are not 100% acurate.
I am looking here your advise that which profiling or gc analysis tool is better in respect to jdk 1.5 and 1.6.
Also is there any work around in gc switches, so the generated output will be according to gcViewer tool.
Thanks in advance. Have a nice day.
Regards
Vivek

Hi "mshanu" and "amit" Thanks for ur replies Here I m posting the code of "top.jsp"........!!!!
<%@ page errorPage="errordisplay.jsp"%>
<table cellpadding="0"
       cellspacing="0"  height=50 width=780>
       <tbody>
         <tr class="header">
           <td class="logo"><IMG SRC="assets/Logo.gif" BORDER=0 ALIGN=top></td>
           <td align="right"><span class="applicationtitle"><%@ include file="/contents/logo.htm" %></span><br>
           <span class="companyname"><%@ include file="/contents/companyname.htm" %></span></td>
         </tr>
        </tbody>
</table>To include top.jsp I have tried
<jsp:include page="top.jsp" flush="true">
</jsp:include>
         AND       
<%@ include file="top.jsp"%>but none of this worked.
If I remove the include then It is working properly.
But I need inluded file too so that I am wondoring for the solution.
This problem seems very wiered to me. I dont know why it is happening.
This problem is started only when I used the TOMCAT 6.14.
Is it the bug of TOMCAT 6.14 or What somebody Plz help.
I got stuck here.........!!!!!!!!!!
It doesn't seem any problem with top.jsp. As per my thinking the problem is there in include due to that it doesn't compile the JSP page in Tomcat 6.0.
Earlier I am having same code running on the Tomcat 5.0.28 and JDK 1.5.0.
But problem occured when I have used Tomcat 6.x...!!
