I selected some code in the editor and chose Refactor->Extract Function. Instead, I got this: eclipse.buildId=4.4.2.M20150204-1700 java.version=1.7.0_80 java.vendor=Oracle Corporation BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_CA Framework arguments:

Could you please provide a code example that can be used to trigger this error.
(In reply to Sergey Prigogin from comment #1) > Could you please provide a code example that can be used to trigger this > error. Sorry, it's proprietary code involving protobuf-generated headers.
(In reply to Csaba Ráduly from comment #2) Can you extract a simpler example code that still reproduces the problem an can be shared?
