The java-check-environment command doesn't use the slot syntax for emerge when recommending a fix for no system generation-1 VM, instead using version syntax. Viewing the source of java-check-environment showed a list of version syntax packages as well. Reproducible: Always Steps to Reproduce: 1. Ensure no system generation-1 VM is configured. 2. run java-check-environment Actual Results: * No Generation-1 System VM is set! (no /etc/env.d/20java) * It doesn't look like java-config-1 sees any installed VMs. * It is most likely because you don't have a 1.4 JDK installed * This is required for generation-1 to work properly. * You will want to emerge =virtual/jdk-1.4* Expected Results: * No Generation-1 System VM is set! (no /etc/env.d/20java) * It doesn't look like java-config-1 sees any installed VMs. * It is most likely because you don't have a 1.4 JDK installed * This is required for generation-1 to work properly. * You will want to emerge virtual/jdk:1.4 The following code also exists in the source: if [[ ${handle} =~ "^kaffe" ]]; then ATOM=">=dev-java/kaffe-1.1.7" elif [[ ${handle} =~ "^blackdown-jdk" ]]; then ATOM=">=dev-java/blackdown-jdk-1.4.2.03-r12" elif [[ ${handle} =~ "^blackdown-jre" ]]; then ATOM=">=dev-java/blackdown-jre-1.4.2.03-r11" elif [[ ${handle} =~ "^ibm-jdk-bin-1.4" ]]; then ATOM="=dev-java/ibm-jdk-bin-1.4.2.5*" elif [[ ${handle} =~ "^ibm-jre-bin" ]]; then ATOM="=dev-java/ibm-jre-bin-1.4.2.5*" elif [[ ${handle} =~ "^sun-jdk-1.4" ]]; then ATOM="=dev-java/sun-jdk-1.4.2.12*" elif [[ ${handle} =~ "^sun-jre-bin-1.4" ]]; then ATOM="=dev-java/sun-jre-bin-1.4.2.12*" elif [[ ${handle} =~ "^jrockit-jdk-bin-1.4" ]]; then ATOM="=dev-java/jrockit-jdk-bin-1.4.2.11*" elif [[ ${handle} =~ "^(\w+-)+[0-9]+\.[0-9]+" ]]; then ATOM="=${BASH_REMATCH}*" While blackdown is not slotted, and kaffe uses non-standard versions, the other jre's and jdk's all have slots and should be using the slotted syntax.
Created attachment 163771 [details, diff] Updates the version based package references to slotted references where appropriate. I have updated the section that suggests a fix for a missing generation 1 vm and also the list of packages that used the old syntax.
