Alan Bateman commented on SUREFIRE-1424:
----------------------------------------
Tibor - the "Class loaders" section of JEP 261
(http://openjdk.java.net/jeps/261#Class-loaders) has all the details. The
important thing is that the class loader arrangement is identical to past
releases (system/application -> platform -> boot). Custom class loader that use
the default class loader for delegation will not notice. The only code that
will be impacted is code that has been bypassing the delegation and going
directly to the boot loader.
> javax.transaction.TransactionManager not visible with Java9
