solving build errors: two missing symbols and one uninitialized variable

[reeskm]

I'm having minor build errors with a 'mvn clean install'

README.md states: jDOSBox can be used with Java 8 or higher, just make sure threshold under the compiler section of the config is set to 0 I've grep'd and find'd for 'threshold' and 'config' and can't find where to set the threshold.

mvn -v outputs: Apache Maven 3.8.8 (4c87b05d9aedce574290d1acc98575ed5eb6cd39) Maven home: /Users/rees/src/apache-maven-3.8.8 Java version: 1.8.0_392-internal, vendor: OpenLogic-OpenJDK, runtime: /Library/Java/JavaVirtualMachines/openlogic-openjdk-8.jdk/Contents/Home/jre Default locale: en_US, platform encoding: UTF-8 OS name: "mac os x", version: "10.9.5", arch: "x86_64", family: "mac"

So there should be a config file in a folder called .jdosbox in the same directory as the Jar. Have you found that?

no, I don't have any .jdosbox folders in my build tree. So the actual problem are these errors:

After easily fixing the last two build errors by importing java.io.PrintStream and java.io.OutputStream in MainFrame.java, I'm left with the final build error which I don't have enough java experience to fix:

A grep finds the lines in question:

jdosbox/src/main/java/jdos/cpu/CPU.java:2911:    final static private Mapper.MAPPER_Handler CPU_CycleIncrease = pressed -> {
jdosbox/src/main/java/jdos/cpu/CPU.java:2912:        if (!pressed) return;
jdosbox/src/main/java/jdos/cpu/CPU.java:2935:    final static private Mapper.MAPPER_Handler CPU_CycleDecrease = pressed -> {
jdosbox/src/main/java/jdos/cpu/CPU.java:2936:        if (!pressed) return;

Because of the complicated assignment in the function definition, I'm not sure how to easily assign the variable pressed a default value. I'm also not sure what if pressed is even declared anywhere. Hope you can help me out!
