Hi, I'm new to this mailing list and working on a project that makes use of
the SA classes to get stack traces from a paused in flight JVM (we can't
use JDWP). I have observed that if the top frame is in the interpreter it
reports the BCI and line number incorrectly. This is because

PS: should have added a new X86Frame constructor really, may have just been
put off because there is already a four address constructor so would have
had to add dummy argument or something.

s:
- PcDescTest.run(int) @bci=7, line=18 (Compiled frame; information
may be imprecise)
- PcDescTest.() @bci=12, line=10 (Compiled frame)
- PcDescTest.main(java.lang.String[]) @bci=4, line=5 (Interpreted frame)
but as you can see the caller line is now incorrect.

} else {
scope = nm.getScopeDescAt(f.getPC());
}
because mayBeImprecise is only set for the top frame.

Hi, in CompiledVFrame.createStackValue there is the following code:
// First find address of value
Address valueAddr = loc.isRegister()
// Value was in a callee-save register
? getRegisterMap().getLocation(new VMReg(loc.getRegisterNumber()))
// Else value was di
that calls setLocation).

Had a nice simple little reproduction test, went to try it on Java 9
and... oh no, sun.jvm.hotspot.jdi.SACoreAttachingConnector has
disappeared! Has it gone for good?
