I upgraded my PC to Ubuntu 12.04 and restored the backup of my workspace and Eclipse afterwards. Now when I try to start my AppEngine/GWT application I run into a problem with the java security manager.
Caused by: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "accessClassInPackage.sun.security.util")
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:366)

I am using appengine SDK 1.6.4 and Objectify4
My java version is
OpenJDK Runtime Environment (IcedTea7 2.1) (7~u3-2.1-1ubuntu3)
OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode)
I already tried to go back to jdk 6 but that did not help. I also have tried to fix this by making changes to the java.policy file and defining a local policy file. No luck so far. I downloaded the AppEngine SDK sources from svn but the line numbers do not really match, but I can see that a more restrictive securiy manager is setup.
The full stack trace here ... any help appreciated :

After trying different Appengine SDK versions, switching between openJDK 6 & 7 and I finally removed openJDK all along and download Oracle JDK 6, setup JAVA_HOME and PATH.
Oracle JDK works !
So it is a Ubuntu 12.04 / OpenJDK issue.
An old one but i confirm this is also working on windows 10 64bit.
In my case have been able to use Oracle jre-6u45-windows-i586.exe with Firefox 10 and Oracle Forms.
It's the only JRE working all the other JRE results in access denied ("java.lang.RuntimePermission" etc.
Thanks :)

How can I fix this problem?
java.lang.UnsupportedClassVersionError: Unsupported major.minor version 52.0
You're trying to compile and run it with Java 8 which is not yet supported on App Engine. The solution is to use Java 7.
I had this same exact issue, and for some reason I had two different versions of App Engine jars in the classpath. Removed the duplicate, and then worked like a charm. In other words, check to make sure your lib is in good order.

Do you have all the prerequestes required by the Amazon JAVA SDK?
Requires Apache Commons (Codec, HTTP Client, and Logging) third-party
packages, which are included in the third-party directory of the SDK.
Finally hit a github https://github.com/radomirml/aws-sdk-for-gaej which address my problem by providing patched jars
I am trying to use amazone ses for sending emails on google app engine for java but face exception as mentioned below.
This happens on adding required httpcore and htttpclient libraries. What is the way to make it work on GAE?

This is a known issue and Apache HttpClient is not supported out of the box due to the above class restrictions on GAE.
Please look at this thread : How to make an HTTPS call on App Engine that contains information on how you can replace one of the existing classes and workaround this issue.
So i could locate a post mentioning how to run ses on gae at http://radomirml.com/2012/07/31/amazon-ses-service-with-java-on-gae
I get a NoClassDefFoundError using Restlet with Google App Engine and GWT.
I'm trying to get Json respresentations of my objects. The error I get is:
java.lang.NoClassDefFoundError: org/codehaus/jackson/JsonGenerator$Feature
A basic skeleton of the method where I get the error is:
#Get("json")
public Representation getProduct() {
Product product = new Product("whatever");
return new JacksonRepresentation<Product>(MediaType.APPLICATION_JSON, product);
}
Initially I got an error for the JsonFactory class when using only the Restlet provided JAR's. I then downloaded the `jackson-all-1.9.7.jar. That error has since been replaced by this new one.
Any idea what's going on ?? Maybe I'm missing some libraries but I can figure out which ones.
EDIT: Including the stacktrace. I removed all the libs and just ran off the Restlet org.restlet.ext.jackson JAR. Also, to check if the class is available at compile time as implied by the answer below, I tried check for autocomplete for the class and package in Eclipse and it doesn't show anything. I'm assuming this means that its not available at compile time either.

Also, if you look in the lib directory of the Restlet version that you downloaded, you will see a readme.txt that will tell you some of the jars that you need to include when you use various Restlet Extensions. For example, the readme.txt should have something like the following:
org.restlet.ext.jackson (Restlet Extension - Jackson)
org.codehaus.jackson.core_1.9
org.codehaus.jackson.mapper_1.9
Thus, if you are using Jackson with Restlet (org.restlet.ext.jackson.jar), you will also need to include the two other jars listed below it.
This is similar to this problem here: Objectify NoClassDefFoundError
You need to put the jar file under WEB-INF/lib/ and make sure include that the library in your build path. And for the clue, NoClassDefFound means that the library is available on compile time but not on the runtime
I updated the to Restlet 2.0.14 and used the org.codehaus.jackson libraries provided with it instead of the ones from the website.
That seems to fix the problem though I don't know which of the two actions actually did this.
i was looking to find a solution for this problem but seems difficult. I have appengine project working with a servlet that handle registration. When i try to call this servlet i have this log report:

Thanks all
MAVEN SOLUTION:
At pom.xml , set "xml-apis" dependency to version 1.4.01:
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>1.4.01</version>
</dependency>
SOLUTION FOR EVERYONE ELSE:
If not using maven, you can manually add the xml-apis library, version 1.4.01. You will find the jars inside the xml-commons binary package, named "XML Commons External 1.4.01", and you can download it here: http://xerces.apache.org/mirrors.cgi.
Finally, compile and execute your java application/project with this version of the library.
Explanation:
The 1.4.01 version of the xml-apis library, includes the required ElementTraversal class. Other versions like 2.0.0, 1.0.0, etc. do not include it, and the application fails while compiling.
There may be some existing issue with the Xerces parser on GAE. See http://code.google.com/p/googleappengine/issues/detail?id=1367
Maybe the workaround is to ensure that all of Xerces jars (including xml-apis.jar) are in your WEB-INF/lib.
Your issue can be resolved by updating to version 2.11.0.SP5, which already contains the class ElementTraversal.
