A test change from the fix to "8172299: Improve class processing" should be backported to openjdk ARM64 workspace

In the ARM32 workspace we have a fix to "8172299: Improve class processing" in the following changeset: http://hg.openjdk.java.net/aarch32-port/jdk8u/jdk/rev/8a2c97926e63
In that changeset the test "test/java/io/Serializable/serialFilter/SerialFilterTest.java" is altered.

In ARM64 ws we have http://hg.openjdk.java.net/aarch64-port/jdk8u/jdk/rev/094fd7d891b6
The test is NOT altered and because of that it fails.

Please, push the test changes that are made in ARM32 repo to ARM64 repo.
