• chosakanizira chongoyerekeza mu nthawi chotchedwa Graal chitha kugwiritsidwa ntchito papulatifomu ya Linux / x64
• mtundu wosiyanasiyana wamomwe mungasinthire.
• adagawana nawo pulogalamu yama data, yomwe imalola kuti makalasi agwiritsidwe ntchito aikidwe mu fayilo yogawana kuti muchepetse kuyambika ndi zotsalira za mapulogalamu a Java.
• Kudziwitsa za Docker: Pa Linux, JVM tsopano imazindikira yokha ngati ikuyenda mu chidebe cha Docker
