JDK-6496524 - Setting breakpoint in jdb crashes Hotspot JVM
Description
When I tried to reproduce this failure with fastdebug build I got 2 different error messages on different platforms (hs_err_pids are attached):
- vmsqe-b2500-02.russia (solaris-sparc):
#
# An unexpected error has been detected by Java Runtime Environment:
#
#  Internal Error (/BUILD_AREA/jdk7.0/hotspot/src/cpu/sparc/vm/assembler_sparc.cpp, 1925 [ Patched ]), pid=10300, tid=14
#
# Java VM: Java HotSpot(TM) Server VM (1.7.0-ea-fastdebug-b10-fastdebug mixed mode)
#
# Error: assert(false,"error")

- vmsqe-amd-05.russia (linux-amd64):
#
# An unexpected error has been detected by Java Runtime Environment:
#
#  Internal Error (/BUILD_AREA/jdk7/hotspot/src/share/vm/oops/methodOop.cpp, 151), pid=2548, tid=1088649568

#
In attached test thread in debuggee executes following method 'run':

	static int sum;

        public void run() {
->          while (true) {
                sum += new String().hashCode();
            }
        }

debugger in loop several times creates breakpoint for line marked with "->" and waits BreakpointEvent, this test causes VM crash. Test output example:
Event: VMStartEvent in thread main
TestThread: instance of BreakpointEventTest001Debuggee$TestThread(name='TestThread', id=179)
Event: BreakpointEvent@BreakpointEventTest001Debuggee$TestThread:29 in thread TestThread

Comments
EVALUATION Closing as a dup of 6496524: Setting breakpoint in jdb crashes Hotspot JVM The breakpoint at line 29 (bci 17) is the same location as the safepoint. The fix in continuation_for() for deoptimization solves the problem.
