----------------------------------------
Summary: MemoryUtil should not fail on Google App Engine with
NoClassDefFoundError
Key: DROOLS-1297
URL: https://issues.jboss.org/browse/DROOLS-1297
Project: Drools
Issue Type: Enhancement
Components: core engine
Affects Versions: 7.0.0.Beta1, 6.5.0.CR1, 6.4.0.Final
Reporter: Geoffrey De Smet
Assignee: Mario Fusco
MemoryUtil throws this exception on Google App Engine:
{code}
java.lang.NoClassDefFoundError: Could not initialize class
com.google.apphosting.runtime.security.shared.stub.java.lang.management.ManagementFactory
at org.drools.core.util.MemoryUtil.<clinit>(MemoryUtil.java:33)
{code}
because the PermGen check goes the wrong way on GAE.
In the MemoryUtil code on line 33, we need something like:
{code}
if (... || isGAE()) {
...
}
public boolean isGAE() {
String p = System.getProperty("com.google.appengine.runtime.environment");
return p != null && !p.equals("");
}
{code}
On GAE, p is "Development". => act same like isAndroid()
On GCE (= plain old OpenJDK), p is null. => act normally
On plain Fedora with OpenJDK 8, p is null. => act normally
