Hi,

I just have the MA 1.1.1 installed in my Eclipse 3.5.1 on a 64 bit windows server 2003. When I clicked the "Leak Suspects" link on a memory dump, I got below error. The eclipse has been working for months so it self is not a problem. Any help will be appreciated.

System property org.xml.sax.driver not specified (org.xml.sax.SAXException)

Hi,

I just tried installing a fresh Eclipse 3.5.1 Classic IDE, 64 bit, Windows 7 (I don't have Win server 2003 to test) and installed into it MAT 1.1.1 from http://download.eclipse.org/mat/1.1/update-site/.
I can run the Leak Suspects report without problems.
Not sure why you encountered one.
Can you tell me what package of Eclipse you installed and which update site you used for MAT? May be we had different setup.
Meanwhile, you could download and use a standalone MA.

This is what I have on the eclipse:

Eclipse SDK

Version: 3.5.1
Build id: M20090917-0800

I used the same update site as you specified.

Can you tell me where I can get the standard MA?

Thanks.

You can download standalone MA from here http://eclipse.org/mat/downloads.php
I'll look once more into the problem. One more question - what JDK are you using?

It's jdk1.6.0_11.
BTW I am on VMWare workstation of the windows server 2003, it it makes any difference.

Thanks for looking into this.

I dl the standalone version and ran it, it has the exact same problem.

Do I need to set up a global CLASSPATH variable or something like that?

I googled for a while and found some similar complaints, however all I found were when using JDK 1.4.

Can you try to explicitly specify which JDK is used? Open the MemoryAnalyzer.ini file (of the standalone MA) and add two lines in front:
-vm
<path to the bin folder of the 1.6 JDK>

I'm just guessing but I have no better idea at the moment.

I tried both these:
-vmC:\Program Files\Java\jdk1.6.0_11\bin

-vm C:\Program Files\Java\jdk1.6.0_11\bin

None fixed the problem. In fact it doesn't seem to take that path as all. I tried this and it did not complaint at start-up:

-vm C:\Program Files\Java\jdk1.6.0_11\binbad

The parameters should be on separate lines, i.e.
-vm
C:\Program Files\Java\jdk1.6.0_11\bin

If this doesn't help, the only other hint I could find so far was a suggestion to add -Dorg.xml.sax.parser=org.apache.xerces.parsers.SAXParser to the VM options. Not sure if this will help. To add the this option, edit again the MemoryAnalyzer.ini file and add (again two separate lines):
-vmargs
-Dorg.xml.sax.parser=org.apache.xerces.parsers.SAXParser


If neither helps, could you send/paste the log file conent (<MAT>/workspace/.metadata/.log)?

Neither worked. Please see my .ini and log below.

I loaded the standalone version on my 32 bit native 2003 server, and it worked fine on the same dump file.

Only on my 64 bit VMware 2003 server it is not working.

Thanks for your help.

Following a suggestion at http://www.saxproject.org/quickstart.html try
-vmargs
-Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser


Note the org.xml.sax.driver not org.xml.sax.parser

If that doesn't work, does
java org.apache.xerces.parsers.SAXParser

give a NoSuchMethodError i.e. the class does exist, or a NoClassDefFoundError (i.e. the SAX parser doesn't seem to be available in the JVM)?

Hi,

I am happy to report back below settings in MemoryAnalyzer.ini work for the standalone one. Sorry I mixed it with the Eclipse plugin before.

Can you tell me how to make the Eclipse plugin work? I can't find a MemoryAnalyzer.ini under Eclipse.

Thanks!

hi,

Under Eclipse there should be a config.ini file with the same function. Save a copy of you current one and try to add the modifications there.
