Michael Osipov updated MNG-5825:
--------------------------------
Description:
MNG-5790 introduced jvm.config (+1) but how it currently handles MAVEN_OPTS and
jvm.config is quite simple, in that it just concats the two values together.
The problem being, if you have:
export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=512m"
jvm.config = -Xmx2048m -Xms2048m -XX:MaxPermSize=512m -Djava.awt.headless=true
You get a Java issue:
localhost:project garethah$ mvn clean install
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
Do to the fact that the command line has multiple options for the same JVM
option.
Can this be improved, so it takes the higher of the values?
