I have an odd issue that only started occurring on M7 and has continued to
RC2. I have a bundle that exposes a service that initializes an MBean
Server.

Under M6 and previous builds this works perfectly fine, on M7 and RC2 I
get the following error

Nested Exception:
java.lang.NoClassDefFoundError: javax/management/MBeanServer
at
com.bf.service.management.jmx.JMXService.initialize(JMXServi ce.java:33)
at com.bf.service.management.jmx.Activator.start(Activator.java :25)
at
org.eclipse.osgi.framework.internal.core.BundleContextImpl$2 .run(BundleContextImpl.java:999)
at java.security.AccessController.doPrivileged(Native Method)
at
org.eclipse.osgi.framework.internal.core.BundleContextImpl.s tartActivator(BundleContextImpl.java:993)
at

etc etc

If I take the same code, and run under Equinox M6 its fine, if I run under
Equinox M7 it breaks. I have tried re-compiling under both versions, I
have double checked that there are no differences in the classpath,
config.ini etc and its all the same..

Anyone any ideas ??

Thanks
Karl

Just some additional information on the previous post..

Under M6 I get the following..

id State Bundle
0 ACTIVE org.eclipse.osgi_3.3.0.v20070321
1 ACTIVE org.eclipse.equinox.log_1.0.100.v20070226
2 ACTIVE org.eclipse.osgi.services_3.1.100.v20060918
3 ACTIVE com.bf.service.management.jmx_1.0.0

Very bare bones JMX Management plugin

Under M7 and RC2..

id State Bundle
0 ACTIVE org.eclipse.osgi_3.3.0.v20070523
1 ACTIVE org.eclipse.equinox.log_1.0.100.v20070226
2 ACTIVE org.eclipse.osgi.services_3.1.100.v20060918
3 RESOLVED com.bf.service.management.jmx_1.0.0

The only change has been in org.eclipse.osgi.

Bundle 3 generates the NoClassDefFound error..
