  JAXP 1.1 method TransformerException.initCause(Throwable) doesn't throw
IllegalStateException for instance that was created with TransformerException(Exception)
constructor as well as it throws this exception for instance that was created with
TransformerException(String) constructor. See log below.
This contradicts JAXP 1.1 spec.
JAXP 1.1 spec reads:
" This method can be called at most once. It is generally called from within the
constructor, or immediately after creating the throwable. If this throwable was
created with TransformerException(Exception) or TransformerException(String,Exception),
this method cannot be called even once.
  Throws:
IllegalStateException - if this throwable was created with
TransformerException(Exception) or TransformerException(String,Exception),
or this method has already been called on this throwable."
This bug presents in build jaxp-1.1ea2-b15-30_nov_2000 and affects the new test in
TCK JAXP 1.1.
