Re: [mat-dev] Find Class object by class name

[Kevin Grigorenko <kevin.grigorenko@xxxxxxxxxx>]

I don't know of an elegant solution, but here are a few ideas:

1. Open Query Browser > List Objects > with outgoing references > Check "include class instance", although you will also get all instances.

2. Using OQL:

SELECT OBJECTS c FROM INSTANCEOF java.lang.Class c WHERE c.@displayName.contains("class org.apache.commons.logging.impl.Jdk14Logger ")

Hi,

I'm using MAT to debug a permgen memory leak. I have found it a
constant pain to find Class objects by class name - I have to start
from the leaking classloader and click all the way through.

Question: say, I suspect there are two copies of A.class, how can I
find all the A.class objects? In other words, how can I find all the
Class objects who represent the class A?

Thanks,
Tony
