Need to verify ThreadLocals in tdump

Hello Dileep Kumar,

I think you need to verify in the heap dump, not in the thread dump since the thread dump contains the stack traces of threads. 

Hi Sainath,

Thanks for your reply. Can you guide me on how to check thread context values in a heap dump?

Hi Dileep,

If I have understood your question correctly, you want to see threadLocal's in the thread dump. But I don't think we get threadLocal values in the thread dump file.

Hi Mahesh,

Thanks for your reply. Can you provide an alternative way of how to verify my thread locals (threadcontext) , I can verify them programmatically but I want to cross-verify it too.

Hi Dileep,

I think you can capture heap dump from your application and upload your heap dump to the HeapHero tool. This tool will analyze your heap dump and display report. In the report, go to the What's in your Memory (by class)? section. Please check the attached screenshot for your reference -



In this section, you should see one entry with the class name java.lang.ThreadLocal$ThreadLocalMap. When you click on this class name, it will take you to another page where you should be able to see all your ThreadLocal variables.
