The reason for the crash is that there is not enough space in the code cache and:

AdapterHandlerLibrary::initialize() contains

BufferBlob* buf = buffer_blob(); // the temporary code buffer in CodeCache (line 2420),
which returns NULL. As a result,
CompileBroker::handle_full_code_cache(); in line 2457 is called. Since the default value of UseCodeCacheFlushing is true, NMethodSweeper::handle_full_code_cache(true) is executed.
However, VMThread::_vm_queue is NULL, since void VMThread::create() (which initializes _vm_queue) is called later when starting up the VM.
