jvm - How can i figure out instruction pointer address in the certain part of my java code? -

-

i'm trying memory trace generated java code(jvm) using pin tool(pinatrace). every result of microbenchmarks try figure out traces shows same graphs, , utilizing processbuilder inside java code gives no remarkable results @ least in comparing among different microbenchmarks. realized should extract substantive part(excluding useless part analysis, initializing, accessing jvm in middle of main code....) of code figure out going wrong.

because instruction pointer sent pinatrace @ moment detects memory access, thought getting instruction pointer of substantive part , set parameter information work. finding way(or tool) job driving me crazy, since java not familiar field me....

i've tried ida pro, says input file format wrong, when input .class file. , setting .java file input shows me binary code seems text file converted binary things , nothing. tried install idajava addon not work....... there easy method ip instead? want know ip java code..

thank you!

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
