BDB JE 7.3.7 and Azul Zulu.

Hi,
I was trying to use BDB JE 7.3.7 with Azul Zulu (based on OpenJDK) and it fails to start with the following error message :
The database environment could not be opened: java.lang.IllegalStateException: Could not access Zing management bean. Make sure -XX:+UseZingMXBeans was specified.
Looking at the code, in src/com/sleepycat/je/utilint/JVMSystemUtils.java, I see that the Zing JVM is detected uniquely based on the java.vendor property. But Azul Systems now produces 2 JVMs.
A possible solution is to change the code has below:
--- a/src/com/sleepycat/je/utilint/JVMSystemUtils.java
+++ b/src/com/sleepycat/je/utilint/JVMSystemUtils.java
@ import java.util.List;
public class JVMSystemUtils {
public static final boolean ZING_JVM =
- "Azul Systems, Inc.".equals(System.getProperty("java.vendor"));
+ "Azul Systems, Inc.".equals(System.getProperty("java.vendor")) &&
+ !System.getProperty("java.runtime.name").startsWith("OpenJDK");
/**
* Zing will bump the heap up to 1 GB if -Xmx is smaller.
Alternately, you could check that the java.runtime.name property contains the string "zing" (although I don't know the exact string for the Zing runtime name).
Thanks.

Hello Ludo,
Thanks for reporting this! I have fixed it, but the fix did not make JE 7.5 so it will go into 7.6.

Thank you Mark. Looking forward to use the out of the box version 7.6.
