RFR: JDK-8252458: Test tools/javac/parser/JavacParserTest.java fails on Windows after JDK-8237041

[Jan Lahoda]

Hi,

In the test for a recently committed JDK-8237041, the result of 
JCTree.toString() is compared with the expected output. But the 
JCTree.toString() uses platform-specific newlines, and the test is not 
compensating that, and fails.

The proposed solution is to normalize the output of JCTree.toString(), 
as other sub-tests of JavacParserTest do.

Proposed webrev:

Thanks for any comments!
