I have a JavaCompute node that depends on some telnet libraries for screen scraping. I can run the desired java code successfully from the Message Broker Toolkit in my unit tests. I have placed the Message Broker jdk (C:\Program Files\IBM\WMBT610\jdk) on my build path in the Message Broker Toolkit, so I am pretty sure I am testing the code with the same jdk version used by the message broker.
However, when I run the code within the JavaCompute node and Exception is thrown with he following error:
| Quote: |
| java.lang.IllegalArgumentException: Signal restricted by VM: INT |
I have two questions:
1. On a windows installation, does the WMB use the same jdk as the default JDK in the Message Broker Toolkit?
2. Does this error indicate some sort of class loading issue or something else?
Here is the entire exception:

Would this by any chance have something to do with java boxing? (int to Integer)? Or not catching an exception on Integer.parse()?
Seems like there might be a method signature discrepancy between the expected signature by the Broker and the actual one?
At the same time, if working in V7, have you thought about the Java class loader service?

You shouldn't have had to do anything specific in the Toolkit to put any particular JVM on the buildpath. That should have been handled correctly when you created a JavaCompute node project.
But if you want to be sure about these things, you should have a local install of Runtime at the same version and be using the Runtime install jdk anyway.
Signal Restriced by VM doesn't sound like a build or jdk incompatibility either. I'm gonna lean more toward's FJ's notion of int vs Integer or etc. |

Thanks for your responses. I do not have access to the source code for the library I am using so it is hard for me to look at the method signatures. What is confusing is that this code runs fine under the same JVM version in Eclipse, but fails in the websphere message broker. I logged the system properties in both to compare the two and the only significant difference I can see is that JIT is disabled in the WMB but is enabled in Eclipse. Could this be a potential problem?
Here are the system setting for the unit test running the code inside Eclipse:

How about you set this property before you run your test from within eclipse.
| Code: |
| -Djava.compiler=NONE |
? How does it work then?

Hi jfrankman -
Did you notice that "ibm.signalhandling.rs=false" in the Eclipse case, whereas it is set to true under WMB?
Follow the link in my next reply to see if you can set "ibm.signalhandling.rs=false". [first post in this forum and board not letting me add a URL]. |

Wow... And you mean to say that you had to use the signal handler and could not use an onDispose or finalize method?

You can suppress signal handling within a JVM by using:
the -Xrs option
the property ibm.signalhandling.sigint set to true / false
the property ibm.signalhandling.rs set to true / false
-----------
For a primer on signals, read:
http://www.ibm.com/developerworks/ibm/library/i-signalhandling/
"When a signal is raised that is of interest to the JVM, a signal handler is called. This handler determines whether it has been called for a Java or non-Java thread. If the signal is for a Java thread, the JVM takes control of the signal handling. If the signal is for a non-Java thread, and the application that installed the JVM had previously installed its own handle for the signal, then control is given to that handler. Otherwise the signal is ignored (even if this is not the signal's default action)."
---------
The native code that is being called from Java could raise a signal (such as a possible signal for closing the telnet session etc) that the JVM need not handle. It is possible that in the case of Eclipse, a signal was being raised and the JVM ignored it because the ibm.signalhandling.rs was set to false.

optimist,
Thank you for your insight. The signal handling settings are definately the source of the problem. Once I set the ibm.signalhandling.rs to true in my Eclipse unit tests I got the exact same behavior. So I tested various combinations of these setting. Here are the results:
| Quote: |
-Xrs - this did not seem to make any difference
-Dibm.signalhandling.rs=false -Dibm.signalhandling.sigint=false //fails
-Dibm.signalhandling.rs=true -Dibm.signalhandling.sigint=false //fails
-Dibm.signalhandling.rs=true -Dibm.signalhandling.sigint=true //fails
-Dibm.signalhandling.rs=false -Dibm.signalhandling.sigint=true //succeeds
-Dibm.signalhandling.rs=false //succeeds
-Dibm.signalhandling.rs=true //fails
-Dibm.signalhandling.sigint=true //succeeds
-Dibm.signalhandling.sigint=false //fails
|
My next question is if/how I can safely change these setting inside the WMB?
Within the JavaCompute node I tried:
| Code: |
| System.setProperty("ibm.signalhandling.rs","false"); |
However, it had no effect. I think this setting needs to get passed into the JVM as a startup parameter. Is there a properties file or something where override this parameter?
fjb_saper:
Thanks for your response as well. Unfortunately, the error is happening inside a third party library, and I don't have access to the source code. So, I don't know why/how they are using signal handling inside of their code. |

| I would also complain to the library vendor if they didn't include specific instructions that their code needed to run in a JVM with this option set. |

I had to upgrade to 6.1.0.8 to be able to change the jvm settings, but once I did I was able to run the following:
| Quote: |
| mqsichangeproperties wbrk61_default_broker -e NexusDev -o ComIbmJVMManager -n jvmSystemProperty -v"-Dibm.signalhandling.rs=false -Dibm.signalhandling.sigint=true" |
Once I did this and restarted the Broker I no longer get the error. Thanks everybody, especially optimist for pointing out the problem and helping me find a suitable fix.
I plan on notifying Jagacy http://www.jagacy.com of this problem with their library documentation. I re-checked their documentation (which is sparse), and could not find any mention of needing to disable the signaling. |
