Below, the autocompletion of REPL suggests that Double.MAX_EXPONENT exists, but this generates an error at bottom.

EDIT: forgot to bracket code correctly.

    cd ; PATH=~/jdk1.7.0_45/bin:~/scala-2.10.3/bin:$PATH scala 
    Welcome to Scala version 2.10.3 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_45).
    Type in expressions to have them evaluated.
    Type :help for more information.

    scala> var e:Double=1
    e: Double = 1.0
{code}Then the workaround suggested #7418:{code}
    scala> e.<TabAutoComplete, the workaround suggested https://issues.scala-lang.org/browse/SI-7418>
    %              *              +              -              /              >              >=             asInstanceOf   isInstanceOf   toByte         toChar         toDouble       toFloat        toInt          toLong         toShort        toString       unary_+        unary_-

Then the autocompletion

    scala> Double.<TabAutoComplete, which generates the bug>
    MaxValue              MinPositiveValue      MinValue              NaN                   NegativeInfinity      PositiveInfinity      asInstanceOf          box                   isInstanceOf          toString              unbox                 MAX_EXPONENT          MAX_VALUE             MIN_EXPONENT          
    MIN_NORMAL            MIN_VALUE             NEGATIVE_INFINITY     POSITIVE_INFINITY     SIZE                  TYPE                  compare               doubleToLongBits      doubleToRawLongBits   isInfinite            isNaN                 longBitsToDouble      parseDouble           toHexString           
    valueOf

And the use, in disagreement with autocompletion

    scala> Double.MAX_EXPONENT
     <console>:8: error: value MAX_EXPONENT is not a member of object Double
              Double.MAX_EXPONENT
                     ^

I wanted to translate eps from matlab, in which eps is the minimal Double that can be added to 1.0, when I found this bug.

@soc said:
The issue is that Scala imports everything in java.lang.*, but shadows things in many cases with their own types in scala._, and then gets confused about which things are accessible.
