The test still fails:

./jdk-9-b123/bin/java -Dtest.timeout.factor=5 bug8078268
Exception in thread "main" java.lang.RuntimeException: Parsing takes too long. Current timeout is 50000
        at bug8078268.main(bug8078268.java:65)


It passes on jdk-9-b123 where [JDK-8078268](https://bugs.openjdk.org/browse/JDK-8078268) is fixed.
