RfR - 8130059: jaxp: Investigate removal of com/sun/org/apache/xalan/internal/xslt/EnvironmentCheck.java

[Daniel Fuchs]

Hi,

Please find below a fix for yet another cleanup for jaxp:

8130059: jaxp: Investigate removal of
          com/sun/org/apache/xalan/internal/xslt/EnvironmentCheck.java
https://bugs.openjdk.java.net/browse/JDK-8130059

http://cr.openjdk.java.net/~dfuchs/webrev_8130059/webrev.00/

EnvironmentCheck doesn't seem to serve any purpose in JDK 9.
It is not called anywhere. The proposal is to remove it.
By doing a full grep on the JDK I also identified another
unused class (Hashtree2Node.java) which referred to EnvironmentCheck
inside a comment.
I took the liberty to remove that class as well.

As for the latter cleanup, what triggered this is that EnvironmentCheck
is using sun.boot.class.path...

best regards,
