Good morning,
I'm entering a new query hoping to receive recommendations. Also, easier to focus on the issue. Please see my previous message, https://www.eclipse.org/forums/index.php/t/1111267/ See previous discussion at, https://bugs.eclipse.org/bugs/show_bug.cgi?id=535351
Although I continue to encounter messages like
Caused by: java.lang.IllegalAccessError: Class com/ibm/dtfj/image/j9/ImageFactory(unnamed module 0x0000000701C2CA68) can not access class jdk/internal/module/Modules(java.base) because module java.base does not export package jdk/internal/module to module unnamed module 0x0000000701C2CA68

I just found a new twist. I downloaded the IBM Semeru DTFJ package located at: https://www.ibm.com/support/pages/node/6537402
Next, simply unzipped and ran MAT. A valid core.dmp opens when selecting Open Heapdump. However, my extended MAT plugin project fails with the above exception after selecting Open Heapdump.
I opened IBM Semeru's MAT_HOME/plugins finding:
• com.ibm.dtfj.api_1.12.29003.202006111057.jar
• com.ibm.dtfj.j9_1.12.29003.202006111057.jar
I'm confused, I thought the IBM Semeru download version may contain updated jar files. I checked a MAT 1.12 installation finding the same jar names.
My question, do I encountered an incompatibility issue causing my exceptions? Please advise and how do I resolve?
Thanks,
Rich Olson
