Thanks for confirming the fix , in addition to your fix a number of new
JEPs have been integrated into JDK 9 b93
I'd like to point you to a few that are now available for testing in
this JDK 9 Early Access build:
JEP 254: Compact Strings (http://openjdk.java.net/jeps/254)
This JEP adopts a more space-efficient internal representation for strings.
We propose to change the internal representation of the String class
from a UTF-16 char array to a byte array plus an encoding-flag field.
The new String class will store characters encoded either as
ISO-8859-1/Latin-1 (one byte per character), or as UTF-16 (two bytes per
character), based upon the contents of the string. The encoding flag
will indicate which encoding is used.
JEP 165: Compiler Control (http://openjdk.java.net/jeps/165)
This JEP proposes an improved way to control the JVM compilers. It
enables runtime manageable, method dependent compiler flags. (Immutable
for the duration of a compilation.)
Method-context dependent control of the compilation process is a
powerful tool for writing small contained JVM compiler tests that can be
run without restarting the entire JVM. It is also very useful for
creating workarounds for bugs in the JVM compilers.
JEP 243: Java-Level JVM Compiler Interface
This JEP instruments the data flows within the JVM which are used by the
JIT compiler to allow Java code to observe, query, and affect the JVM's
compilation process and its associated metadata.
JEP 268: XML Catalog API (http://openjdk.java.net/jeps/268)
This JEP develops a standard XML Catalog API that supports the OASIS XML
Catalogs standard, v1.1. The API will define catalog and
catalog-resolver abstractions which can be used with the JAXP processors
that accept resolvers.
Existing libraries or applications that use the internal API will need
to migrate to the new API in order to take advantage of the new features.
