RFR: JDK-8187883: NewClassDefEnclosing.java fails on windows

[Jan Lahoda]

Hello,

The test for JDK-8044853 is normalizing whitespaces, but is not 
recognizing the Windows line endings. The proposed fix is to use \s+ to 
normalize whitespaces.

Bug: https://bugs.openjdk.java.net/browse/JDK-8187883

Thanks,
