Tristan Tarrant updated ISPN-2237:
----------------------------------
Status: Resolved (was: Pull Request Sent)
Resolution: Done
ConcurrentMapFactory does not allow use of V8 maps with Sun JDK 6
-----------------------------------------------------------------
Key: ISPN-2237
URL:
https://issues.jboss.org/browse/ISPN-2237
Project: Infinispan
Issue Type: Bug
Affects Versions: 5.1.6.FINAL
Reporter: Robert Stupp
Assignee: Galder ZamarreƱo
Fix For: 5.2.0.Alpha4, 5.2.0.Final
The implementation in ConcurrentMapFactory checks for existance of a Sun JVM private
class. But although a Sun JDK/JRE 6 is used, the check fails (wrong class
com.sun.unsafe.Unsafe instead of sun.misc.Unsafe).
Sould use sun.misc.Unsafe
{noformat}
static {
boolean sunIncompatibleJvm;
boolean jdk8;
boolean allowExperimentalMap =
Boolean.getBoolean("infinispan.unsafe.allow_jdk8_chm");
try {
Class.forName("com.sun.unsafe.Unsafe");
sunIncompatibleJvm = false;
} catch (ClassNotFoundException e) {
sunIncompatibleJvm = true;
}
try {
Class.forName("java.util.concurrent.atomic.LongAdder");
jdk8 = true;
} catch (ClassNotFoundException e) {
jdk8 = false;
}
if (jdk8 || sunIncompatibleJvm || !allowExperimentalMap)
MAP_CREATOR = new JdkConcurrentMapCreator();
else
MAP_CREATOR = new BackportedV8ConcurrentMapCreator();
}
