java - Unable to debug attached Source Code(rt.jar). "Unable to install break point due to missing line number" -
i have tried unchecking , checking box inside windows-->preference-->compiler option-->class file generation. tried restarting eclipse.but didnt work. using "eclipse-jee-indigo-sr2-win32-x86_64". have used src zip folder in jdk1.7.0_79.
i want write own program, use map/list etc , debug through methods of these classes , see how works internally.please help
the message complaining java runtime not having debugging information. attaching source not fix problem, enable read source. didn't compile classes using eclipse, preference has no relevance. if want debug rt.jar, need install , compile/run against jdk, not jre, , if have jdk installed, sounds not being used run java application. check installed jres preference page (hint: prefer having jdks there) , application's launch configuration make sure it's using expect.
