Hello,

Our product currently uses Tomcat 8.5.83. We wanted to upgrade to Tomcat 8.5.88 
but our product fails to start up with this version.

>From my research I was able to determine the following facts:
- Upgrade to 8.5.84 works fine
- Upgrade to 8.5.85+ fails
- Our product uses "tomcat8.exe //US/vlm" to update the service parameters (vlm 
is the internal name of our product)
- with 8.5.85, calling the following command works fine: tomcat8.exe //US/vlm 
--Description myDescription
- setting java parameters don't work however, for example this command fails: 
tomcat8.exe //US/vlm --JvmMs 128
- when running the command above, tomcat8.exe does not display an error but the 
service is not updated
- the documentation at 
https://tomcat.apache.org/tomcat-8.5-doc/windows-service-howto.html indicates 
that the java update parameters are not set when in exe mode but ours is in jvm 
mode. For example, the following command will not set the JvmMs value: 
tomcat8.exe //US/vlm --Jvm auto --StartMode jvm --StopMode jvm --JvmMs 128

Does anyone have any info on how to get around this?
Otherwise, can someone direct me to the source code for tomcat8.exe so I can 
see if I can find the cause of this issue myself?

Thank-you,

Gilles Maurice
