[libvirt] JVM crashes during GC

[Sachin Soman]

Hi,

Could you tell me if the following is some known issue?

While performing the following simple test, I see my JVM crashing
(consistently):
1. Open a connection to an ESXi driver/host (passing ConnectAuthDefault
instance).
2. Close the connection.
3. Invoke GC

When GC is triggered, at some point, some unallocated native memory is
being tried to release. That's failing.

The error thrown is:

java(78745,0x70000241e000) malloc: *** error for object 0x7fd5df561390:
pointer being freed was not allocated

*** set a breakpoint in malloc_error_break to debug
