Relevant part of the backtrace seems to be: #7 <signal handler called> No symbol table info available. #8 ciTypeFlow::build_loop_tree (this=<value optimized out>, blk=<value optimized out>) at /usr/src/debug/icedtea6-1.6/openjdk/hotspot/src/share/vm/ci/ciTypeFlow.cpp:2482 lp = 0x0 succ = <value optimized out> iter = {<StackObj> = {<No data fields>}, _pred = 0xa5a1e58, _index = 0, _succ = 0x9f35628} innermost = <value optimized out> #9 0x00d0785e in ciTypeFlow::df_flow_types (this=<value optimized out>, start=<value optimized out>, do_flow=<value optimized out>, temp_vector=<value optimized out>, temp_set=<value optimized out>) at /usr/src/debug/icedtea6-1.6/openjdk/hotspot/src/share/vm/ci/ciTypeFlow.cpp:2635 blk = <value optimized out> root_head = <value optimized out> root_tail = <value optimized out> next_po = <value optimized out> stk = {<GenericGrowableArray> = {<ResourceObj> = {<No data fields>}, _len = 2, _max = 100, _arena = 0x7ebf5c}, _data = 0xa5a1900} dummy = <value optimized out> root_set = <value optimized out> size = <value optimized out> #10 0x00d08093 in ciTypeFlow::flow_types (this=<value optimized out>) at /usr/src/debug/icedtea6-1.6/openjdk/hotspot/src/share/vm/ci/ciTypeFlow.cpp:2670 start = <value optimized out> start_state = 0x9f35628 #11 0x00d0817d in ciTypeFlow::do_flow (this=<value optimized out>) at /usr/src/debug/icedtea6-1.6/openjdk/hotspot/src/share/vm/ci/ciTypeFlow.cpp:2831 No locals. #12 0x00cf20f8 in ciMethod::get_osr_flow_analysis ( this=<value optimized out>, osr_bci=<value optimized out>) at /usr/src/debug/icedtea6-1.6/openjdk/hotspot/src/share/vm/ci/ciMethod.cpp:333 env = 0x7ebf58 flow = <value optimized out> #13 0x00fed47e in Parse::Parse (this=<value optimized out>, caller=<value optimized out>, parse_method=<value optimized out>, expected_uses=<value optimized out>) at /usr/src/debug/icedtea6-1.6/openjdk/hotspot/src/share/vm/opto/parse1.cpp:451 entry_map = 0x9f35628 log = 0x0 md = <value optimized out> caller_nn = 0x10 entry_block = <value optimized out>
So we get lp = 0x0 at ciTypeFlow.cpp:2482 // Check for irreducible loop. // Successor has already been visited. If the successor's loop head // has already been post-visited, then this is another entry into the loop. while (lp->head()->is_post_visited() && lp != loop_tree_root()) { And obviously dereferencing lp isn't going to work... Might this be http://bugs.sun.com/view_bug.do?bug_id=6854812 ? It might or might not, the symptom seems to be the same (lp being NULL), but we are seeing it at the start of the while loop, while in that case it is observed (through an assert) at the end of that same loop.
(In reply to comment #1) > Created an attachment (id=377351) [details] > File: backtrace Usually, this crash happens when the network condition is bad or the network simply goes down. Actually, the BT software makes the network down in the first place.

If this is the same bug I've run into, it is super easy to reproduce. Just have Vuze running, suspend your system, then restart it. It generally crashes within a few minutes of restarting. What I can read on the stack traces seem to point at network things being the cause. It must be when the network is getting reconnected after the suspend. I also filed a bug about this with Iced Tea. http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=422 I've since switched over to the Sun JDK 1.6.0_18 a few days ago and it hasn't crashed at all while restarting after a suspend.

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
