Using libjvm.diz in gdb

[Douglas Simon]

I've just encountered the new Full Debug Symbols support in HotSpot and am having trouble using it with gdb. When I start gdb on a debug build (i.e. jvmg) of HotSpot, I also load the unzipped libjvm.diz file as follows:

~/linz/graalvm$ gdb jdk1.7.0_06/debug/bin/java
(gdb) symbol-file /mnt/ubuntu-10.04/home/dsimon/linz/graalvm/jdk1.7.0_06/debug/jre/lib/amd64/graal/libjvm.debuginfo
Reading symbols from /mnt/ubuntu-10.04/home/dsimon/linz/graalvm/jdk1.7.0_06/debug/jre/lib/amd64/graal/libjvm.debuginfo...done.
(gdb) b methodDataOop.cpp:870
Cannot access memory at address 0x573d06

Naturally, the program never stops at the line where I'm trying to set the breakpoint.

What am I doing wrong? Is there some information on how one is supposed to use FDS for debugging under gdb (or dbx)?
