Issue Description
JDK-8244336

New Security Property "jdk.crypto.disabledAlgorithms" for Restricting Algorithms at the JCE layer


A new security property named jdk.crypto.disabledAlgorithms has been introduced to disable algorithms for JCE/JCA cryptographic services. Initially this property only supports the Cipher, KeyStore, MessageDigest, and Signature services. This property is defined in the java.security file and initially no algorithms are disabled by default. However, this may change in the future. This security property can be overridden by a system property of the same name if applications need to re-enable algorithms.

Issue Description
JDK-8212084

G1: Support UseGCOverheadLimit


The G1 garbage collector now throws an OutOfMemoryException when the garbage collection overhead is more than GCTimeLimit percent (default value 98) and the free Java heap is less than GCHeapFreeLimit percent (default value 2) for five consecutive garbage collections.

This feature is enabled by default. It can be disabled using the -XX:-UseGCOverheadLimit option.

The implementation mirrors the functionality already provided by the Parallel garbage collector. However there may be differences in the exact conditions for the OOME triggers as G1 calculates garbage collection overhead and free Java heap slightly differently.
