Comment 2 ilia 2016-07-18 16:59:47 UTC 
Some results after investigation of this bug:

In LibraryChecker.isLibraryAvailable the dummySourceFile variable seems to be null. It may be null after calling the convertToCompilerPath method, which returns null in case the activeShell is null if we are converting to/from Cygwin path. 

Preliminary conclusion:
Cygwin paths in a toolchain may be corrupted.
Comment 3 ilia 2017-06-26 09:38:21 UTC 
Able to reproduce the exception: happens if WindowsSupport.findShell returns null. It seems this exception can also occur when toolchain validates for too long (and both users reported this exception complain about long validation). In this case currentShell is just not initialized yet and we get an NPE.
Comment 4 Quality Engineering 2017-07-20 17:51:54 UTC 
Integrated into 'main-silver', will be available in build *201707201608* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
