[jdk8u-dev] RFR: 8274606: Fix jaxp/javax/xml/jaxp/unittest/transform/SurrogateTest.java test

[Kazuhisa Takakuri]

This is a backport of JDK-8274606: Fix jaxp/javax/xml/jaxp/unittest/transform/SurrogateTest.java test.
This patch compliments JDK-8268457, which I have already proposed for backporting. #517
This backport is not clean due to the fact that the JDK-8268457 backport is not clean.

I confirmed that SurrogateTest.java fails in the build before applying JDK-8268457 and succeeds in the build after applying it.

Testing: All tests under jdk/test/javax/xml/jaxp/

Thank you.
