[news.eclipse.tools.pdt] Re: XDebug JIT Debugging Issue

[Dave Kelsey <dkel50@xxxxxxxxxxx>]

Hi Shawn, this behaviour is due to the Remote Session initiation only having a dummy source locator 
defined to it. The source locator is used to locate and open the appropriate source file and it 
fails to find the file (because it is only a dummy source locator for this session) so falls back on 
the remapped file (by the path mapper) and opens that absolutely instead.

Could you raise a bugzilla, https://bugs.eclipse.org/bugs/enter_bug.cgi?product=PDT , to request an 
enhancement to this ?

Many thanks for looking into this, your explanation and determination of the cause were spot on.

Cheers
Dave Kelsey
