IntelliJ - debug mode - search text in program memory

Question

I'm working with undocumented 3rd party library. I know that there is a certain String stored somewhere in one of the fields deep in the library (dynamic value that I can predict, but I want to get it from the API of the library).

Is there a way to search (something like fulltext search?) through the full program memory while in the debug mode and while stopped on certain breakpoint? I want to find which field in which object actually stores this value.

(I know I could do manual dump and grep, I'm more interested if IntelliJ supports this feature)

No, there is no such feature in IntelliJ IDEA. – yole Sep 27 '16 at 15:19 — yole, Sep 27 '16 at 15:19

IntelliJ 2015 and 2016 can decompile Java classes, so you can get the string from the library ~~without debugging at all~~. Use Navigate -> Declaration or Navigate -> Implementation(s) to see a decompiled version of the byte code for the class. The decompiler can get everything except the original variable names and comments from a library.

This String is dynamic, it should be known when I'm waiting on the breakpoint – Piotr Reszke Sep 27 '16 at 15:24
Debugging can use use the decompiler as well to find the code with the variable. You may need to walk up the stack to find which method has the string. – Michael Shopsin Sep 27 '16 at 17:55
