Sorry, Mark. I should have provide that information upfront. I am using: Tomcat 7.0.55 JRE version: Java(TM) SE Runtime Environment (8.0_92-b14) (build 1.8.0_92-b14) OS version: Windows Server 2012 R2 > I produced the binaries for the most recent of those and I probably > still have the necessary files sat on a VM if they are recent(ish). > > Mark Yeah, I know it's not that recent. Still, if you have it please let me know. We tried to create PDB files for Java specific DLLs from OpenJDK, but as you can see below, WinDbg rejected it. ************* Symbol Loading Error Summary ************** Module name Error tomcat7 No header information available : srv*c:\mss*http://msdl.microsoft.com/download/symbols jvm Signature does not match : srv*c:\mss*http://msdl.microsoft.com/download/symbols tcnative-1 No header information available : srv*c:\mss*http://msdl.microsoft.com/download/symbols Thanks!
