java - Hex values instead of line numbers in the stack trace -


i trying debug java program loaded embedded system reading output via serial port. when exception raised cannot see line numbers in stack trace. instead there hexadecimal values. suspect maybe stand memory addresses, not sure @ all. here portion of stack trace give idea:

exception in thread "main" com.is2t.web.rs.restexception      @ java.lang.system.@m:0x8009e7c:0x8009e86@      @ java.lang.throwable.@m:0x8009f88:0x8009f9e@      @ java.lang.throwable.@m:0x8008cec:0x8008cfe@

is there way view line numbers? if not, best technique debug without knowing them?

edit: embedded system stm32 microcontroller , don't believe have documentation explaining particular situation.
