This is the sixth in a series of fixes for JEP 232 (Improve Secure
Application Performance) [1].
webrev: http://cr.openjdk.java.net/~mullan/webrevs/8072692/webrev.00/
bug: https://bugs.openjdk.java.net/browse/JDK-8072692
This fix adds several optimizations to the package matching algorithm
used by the SecurityManager.checkPackageAcccess method. These
improvements result in a 5-7x increase in throughput of this method. A
performance chart has been attached to the bug with more information.
A new test is included which uses a state machine to verify that the
matching algorithm is working correctly.
Special thanks to Daniel Fuchs for contributing this fix and the test.
Thanks,
Sean
