Re: nonce cache thread proliferation

[Colm O hEigeartaigh]

Which cache are you expecting to get invoked? The SAML cache only gets
invoked if there is a "OneTimeUse" attribute on a SAML Assertion. The
UsernameToken cache gets invoked only if there is a nonce in the
UsernameToken. The Timestamp cache gets invoked only if there is both a
Signature + Timestamp, where the Signature signs the Timestamp.

 I'm a bit confused by this. Why is the diskstore shutting down after
 every invocation? Are you seeing a new cache file created for each
 invocation?

Hi, 

Yes, I am not importing CXF, I am using wss4j as standalone library.

Many thanks for the fix, I will try it ASAP. Is it available already in 2.0.9?

An additional point: it seems not to be related to wildfly. The same code

Re: nonce cache thread proliferation

Hi, 

I performed the following tests. 

1) See which executor service is parked, using jconsole and visual vm.

The exception is the following: 
Name: wss4j%002etimestamp%002ecache-%004crxid%0045s%004ccr%004ci%0041g==.data

State: TIMED_WAITING on

The visualvm output is here: 
https://dl.dropboxusercontent.com/u/1942406/visualvm.png

2) Change to 2.8.5, and observe the output. Same exception, 

https://dl.dropboxusercontent.com/u/1942406/visualvm_parked.png
https://dl.dropboxusercontent.com/u/1942406/live.png


3) Set the inmemory only cache. I am not sure here, I recompiled by changing the

cat wss4j-ehcache.xml 











With the same results. Is there another way to set it up, or to not use 
ehcache, but another caching mechanism? For instance, I see the 
MemoryReplayCache that can be used to test. 



In my opinion the issue seems to be related to ehcache. I don’t think that it 
can be due to my programming mistakes. 

Here is my code: 

WSSConfig config = WSSConfig.getNewInstance();

config.setProcessor(new QName(WSConstants.SAML2_NS, 
"Assertion"), LocalSAMLTokenProcessor.class);
config.setProcessor(WSSecurityEngine.SAML_TOKEN, 
LocalSAMLTokenProcessor.class);

WSSecurityEngine secEngine = new WSSecurityEngine();
secEngine.setWssConfig(config);
RequestData rd = new RequestData();
rd.setEnableNonceReplayCache(true);
rd.setEnableSamlOneTimeUseReplayCache(true);
rd.setEnableTimestampReplayCache(true);
rd.setCallbackHandler(cbHandler);
rd.setSigVerCrypto(fakeCrypto);
rd.setDecCrypto(fakeCrypto);
rd.setActor(null);



List results = 
secEngine.processSecurityHeader(WSSecurityUtil.getSecurityHeader(envelope, 
null), 
rd);


Thanks again!

Re: nonce cache thread proliferation

[Colm O hEigeartaigh]

Hi Massimiliano,

This sounds like a serious problem, although possibly EhCache related
rather than WSS4J.

Firstly, WSS4J 2.0.7 uses EhCache 2.8.5 not 2.9.0 - could you verify that
the same behaviour occurs with 2.8.5?

If you disable the diskstore by changing the EhCache configuration, does it
solve the problem?

nonce cache thread proliferation

[massimiliano.masi]

Hi All, 

I updated from wss4j 1.6 to wss4j 2.0.7. I observe the following behaviour 
(using wildfly 9 and java 1.8.0_60). 

With Nonce Replay Cache, Saml One Time Use Replacy Cache, Timestamp Replay 
Cache set to true, there is a linear thread proliferation: 1 call, 1 thread 
open and not closed. 

With all those caches set to false, the threads are not proliferating and 
everything is fine. 

Threads are watched as: watch -n 1 “date && cat /proc//status | grep 
Threads”

In fact, ehcache is using a new ScheduledThreadPoolExecutor (version 2.9.0 
net.sf.ehcache.store.disk.DiskStorageFactory, line 151) and it is assigned to a 
private final (non static) variable. Analyzing the JVM with VisualVM we 
observed that, when the shutdown() 
of the ExecutorService was called, the active threads were parked, causing a 
new creation of another executor service for a new session. 

Thus the linear proliferation observed seems to be a new instance of the 
ScheduledThreadPoolExecutor. 

Thus: 2000 web service requests, 2000 new threads spawned and not closed. 

Any advice?

Thanks a lot, 

Massimiliano
