I was digging around trying to figure out some strange error with a saml integration when I came across the verifyAudience Method of the spring-security-saml/core/src/main/java/org/springframework/security/saml/websso/WebSSOProfileConsumerImpl.java

I had never noticed this particular usage of Java in the wild with a loop inside a loop with a continue statement.

I've created an example in groovy because I'm lazy:

List restrictions = [1,2,3,4,5]
List selections = [3,5]

audience:
for(int a in restrictions){
for(int b in selections){
if(a==b){
println "skip"
continue audience
}
println "$a -- $b"
}
}

Here is the Output:
1 -- 3
1 -- 5
2 -- 3
2 -- 5
skip
4 -- 3
4 -- 5
5 -- 3
skip

Some info from Stackoverflow

keytool -delete -alias -keystore lib/security/cacerts -storepass changeit

There's a nice description of the different types of timeouts that can be used with HttpClient at baeldung.com

Interestingly, an out of memory error doesn't cause the jvm to exit, but, you can make it do so if you want. Here is a writeup about doing so at thinkingInSoftware.blogspot.com

To customize what version of Java is used by default on your mac (once you've installed another version of Java):
At the command line:
cd /System/Library/Frameworks/JavaVM.framework/Versions
sudo rm CurrentJDK
sudo ln -s /Library/Java/JavaVirtualMachines/jdk{version number here}.jdk/Contents CurrentJDK

For those updating their Macs to Yosemite it will revert the CurrentJDK symlink to the system default even if you have customized it.

Posting this because a friend needed it... I would never advocate using such a platform :)

Verified by creating the following class

import javax.crypto.*;
import java.security.*;
public class JceTest {
public static void main (String[] args){
boolean isUnlimitedSupported = false;
try {
KeyGenerator kgen = KeyGenerator.getInstance("AES", "SunJCE");
kgen.init(256);
isUnlimitedSupported = true;
} catch (NoSuchAlgorithmException e){
isUnlimitedSupported = false;
} catch (NoSuchProviderException e) {
isUnlimitedSupported = false;
}
System.out.println("isUnlimitedSupported=" + isUnlimitedSupported);
}
}

and running: javac JceTest.java; java JceTest
