Losing cause exception stack traces

This is a stack trace I've got:

SEVERE: Error while training classifier model 9
org.cleartk.classifier.encoder.CleartkEncoderException: Invalid value in 
feature vector 9:?

        at java.lang.Thread.run(Thread.java:722)

Looking at line 101 of FeatureVectorFeaturesEncoder.java, I see 

catch (InvalidFeatureVectorValueException e) {
        throw CleartkEncoderException.invalidFeatureVectorValue(e.getIndex(), e.getValue());
      }

So there was an exception which caused this, but I don't have its stack trace! 
I suggest that static methods in CleartkProcessingException and 
CleartkEncoderException should all take Throwable cause as an argument.

Alexey, thank you for filing the issue and for identifying the fix.  This seems 
like a very straightforward and sensible suggestion.  Apologies for the delay 
in getting it fixed.

CleartkEncoderException.invalidFeatureVectorValue has two signatures now - one 
that now takes a throwable.  This will help debugging when 
FeatureVectorFeaturesEncoder.encodeAll throws it (it now passes the cause).  
This handles the complaint that initiated this issue.
CleartkProcessingException.unsupportedOperationSetParameter now takes a 
Throwable param.  The only caller of this method was inside a catch block.
I left CleartkProcessingException.noInstanceOutcome alone because no callers of 
the method were catching another exception - i.e. the method was not being 
called in a catch block
I also stumbled on a bug in a CleartkEncoderException constructor in which the 
parameters were in the wrong order
