PyDev 5.7.0.20170411357 No Longer Supports IronPython - pydev

Question

I recently upgraded my PyDev plugin to version 5.7.0.20170411357.
It seems IronPython is no longer supported.
I'm using Eclipse Oxygen
Does anyone have a workaround?
When starting the debugger the following message is displayed:
RuntimeError: Unable to proceed (sys._current_frames not available in this Python implementation).
Yes, I am adding the Vm argument -x:Frames.
The error is thrown from pydevd_additional_thread_info_regular.py
There is an accommodation for Jython.
if not hasattr(sys, '_current_frames'):
# Some versions of Jython don't have it (but we can provide a replacement)
if IS_JYTHON:
from java.lang import NoSuchFieldException
from org.python.core import ThreadStateMapping
try:
cachedThreadState = ThreadStateMapping.getDeclaredField('globalThreadStates') # Dev version
except NoSuchFieldException:
cachedThreadState = ThreadStateMapping.getDeclaredField('cachedThreadState') # Release Jython 2.7.0
cachedThreadState.accessible = True
thread_states = cachedThreadState.get(ThreadStateMapping)
def _current_frames():
as_array = thread_states.entrySet().toArray()
ret = {}
for thread_to_state in as_array:
thread = thread_to_state.getKey()
if thread is None:
continue
thread_state = thread_to_state.getValue()
if thread_state is None:
continue
frame = thread_state.frame
if frame is None:
continue
ret[thread.getId()] = frame
return ret
else:
raise RuntimeError('Unable to proceed (sys._current_frames not available in this Python implementation).')
else:
_current_frames = sys._current_frames
