Med JPype kan man fra Python bruge Java-specifikke biblioteker og skabe hybride applikationer, der kombinerer kode skrevet i Java og Python. I mods\u00e6tning til Jython opn\u00e5s integration med Java ikke ved at skabe en variant af Python til JVM, men gennem interaktion p\u00e5 niveauet for begge virtuelle maskiner ved hj\u00e6lp af delt hukommelse. Den foresl\u00e5ede tilgang muligg\u00f8r ikke kun god ydeevne, men giver ogs\u00e5 adgang til alle CPython- og Java-biblioteker. Projektkoden <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/jpype-project\/jpype\/\">distribueres<\/a><\/noindex> er under Apache 2.0-licensen.<\/p>\n<p>Vigtige \u00e6ndringer:<\/p>\n<ul>\n<li class=\"l\"> Undtagelser, der kastes i C++ og Java-kode, giver nu en undtagelsesstak, n\u00e5r der opst\u00e5r en undtagelse i Python-koden. Derfor er det ikke l\u00e6ngere n\u00f8dvendigt at kalde stacktrace() for at f\u00e5 information om undtagelsesstakken.\n<li class=\"l\"> Hastigheden for tilbagevenden ved kald er tredoblet.\n<li class=\"l\"> Hastigheden for overf\u00f8rsel til<br \/>\nnumpy-buffere af multidimensionale arrays er v\u00e6sentligt (flere st\u00f8rrelsesordener) forbedret. Multidimensionale prim\u00e6re typer sender nu kun-l\u00e6se kopier, der er skabt inden for JVM med kontinuerlig C-layout.<\/p>\n<li class=\"l\"> Alle interne komponenter er blevet udskiftet med implementeringer fra CPython, og symbolerne __javaclass__, __javavalue__ og __javaproxy__<br \/>\ner blevet fjernet. Alle CPython-typer, der er arvet fra jpype-klassetyper, har f\u00e5et en dedikeret Java-slot. Alle private tabeller er blevet overf\u00f8rt til CPython. Java-typer skal nu arve fra metaklassen JClass, som bruger type-slotte. Mixins for Python-basis klasser er ikke tilladt. Typerne Object, Proxy, Exception, Number og Array arves direkte fra de interne CPython-implementeringer.<\/p>\n<li class=\"l\"> Sporing og h\u00e5ndtering af undtagelser er forbedret.\n<li class=\"l\"> Array slices behandles nu som visninger, der underst\u00f8tter tilbagef\u00f8ring til originalen, s\u00e5som numpy arrays. Der er tilf\u00f8jet underst\u00f8ttelse af at s\u00e6tte og f\u00e5 v\u00e6rdier med trin (slice(start, stop, step)) for array slices.\n<li class=\"l\"> I arrays er support for \u00ab__reversed__\u00bb blevet implementeret.\n<li class=\"l\"> I Java-arrays er der tilf\u00f8jet st\u00f8tte for memoryview API, og afh\u00e6ngigheden af numpy til overf\u00f8rsel af bufferindhold er fjernet.\n<li class=\"l\"> Numpy er nu ikke l\u00e6ngere en afh\u00e6ngighed (ekstra), og overf\u00f8rsel af hukommelse til numpy er tilg\u00e6ngelig uden at kompilere med numpy-underst\u00f8ttelse.\n<li class=\"l\"> JInterface er udformet som en metaklasse. Brug isinstance(cls, JInterface) til at tjekke for interfaces.\n<li class=\"l\"> Standard importerne er blevet tilf\u00f8jet de udeladte TLD \u00abmil\u00bb, \u00abnet\u00bb og \u00abedu\u00bb.\n<li class=\"l\"> Fejlmeddelelser for UnsupportedClassVersion er forbedret under opstart.\n<li class=\"l\">    java.util.Map kaster nu KeyError, hvis elementet ikke findes. V\u00e6rdier, der er null, returnerer stadig None som forventet. Brug get(), hvis tomme n\u00f8gler skal behandles som None.\n<li class=\"l\"> java.util.Collection er fjernet, da den underligt overbelastes mellem remove(Object) og remove(int) p\u00e5 lister. Brug Java-metoden remove() for at f\u00e5 adgang til den originale Java-adf\u00e6rd, men typecasting anbefales kraftigt for at styre overbelastningen.\n<li class=\"l\"> java.lang.IndexOutOfBoundsException kan nu fanges ved hj\u00e6lp af klassen for undtagelser IndexError ved adgang til elementer i java.util.List.\n<\/ul>\n<p><noindex><a rel=\"nofollow\"
