CLOCKTREETOOL: Will not execute, Execption when executing

Joseph Ott

Hello,

I am trying to run the Clock Tree Tool but get an exception when trying to run.

To see why the Clock Tree tool wasn't running I tried running from a command prompt to capture the output.

C:\Utilites\TI_Clock_Tree_Tool\CTT-Sitara-v1.0.0.9>java -jar CTT-Sitara-Legacy.jar
Exception in thread "main" java.lang.IllegalAccessError: class org.ti.clockTreeTool.SiliconRevision_XMLParser.ParserSiliconRevision_XML (in unnamed module @0x617faa95) cannot access class com.sun.org.apache.xerces.internal.parsers.DOMParser (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.parsers to unnamed module @0x617faa95

I see the same exception when running

C:\Utilites\TI_Clock_Tree_Tool\CTT-Sitara-v1.0.0.9>java -jar CTT-AM65.jar
Exception in thread "main" java.lang.IllegalAccessError: class org.ti.clockTreeTool.SiliconRevision_XMLParser.ParserSiliconRevision_XML (in unnamed module @0x617faa95) cannot access class com.sun.org.apache.xerces.internal.parsers.DOMParser (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.parsers to unnamed module @0x617faa95

at org.ti.clockTreeTool.simulation.ClockTreeTool.main(ClockTreeTool.java:68)

Any idea why I am seeing these exceptions?

The Java version info is

C:\Utilites\TI_Clock_Tree_Tool\CTT-Sitara-v1.0.0.9>java -version
java version "19.0.1" 2022-10-18
Java(TM) SE Runtime Environment (build 19.0.1+10-21)

Hi Joseph,

I am not able to replicate your issue at the moment. I will ask my colleagues for their input.

Did you install the Clock Tree Tool for the first time today or has the tool opened on your computer previously? I'm wondering if there was an error during installation that could be fixed by uninstalling and reinstalling the tool.

Regards,

Megan

Megan,

The Clock Tree tool has never run on my machine. I have tried uninstalling and reinstalling several times.

Hi Joe,

The Clock Tree Tool has not had an update in a few years and therefore may not be compatible with newer versions of Java. We are currently looking into how Java updates may impact the tool. If you are able to revert to Java 8, that is a known version compatible with the Clock Tree Tool.

Regards,

Megan

After talking to our IT department I was able to install Java 8.

The Clock Tree Tool now runs.
