Helpful Nullpointerexceptions In Java 14 That Which Inspires Awe Consequently, the feature was finished and pushed in october 2019 for the jdk 14 release. in essence, jep 358 aims to improve the readability of nullpointerexceptions, generated by jvm, by describing which variable is null. Released in march 2020, java 14 introduced a game changing enhancement to npes: helpful nullpointerexceptions. this feature, defined by jep 358, generates detailed error messages that explicitly identify the null variable or expression, drastically reducing debugging time.
Java 14 Nullpointerexception Detailed Message Devcubicle By Cloud Tech With java se 14, the nullpointerexception offers helpful information about the premature termination of a program. java se 14 onwards, the jvm describes the variable (in terms of source code) with a null detail message in the nullpointerexception. Fortunately, jdk 14 (and subsequent versions) introduced enhanced nullpointerexceptions, a significant improvement that makes debugging npes much more straightforward and less time consuming. Only npes that are created and thrown directly by the jvm will include the null detail message. npes that are explicitly created and or explicitly thrown by programs running on the jvm are not subject to the bytecode analysis and null detail message creation described below. In java 14, a new feature was introduced as helpful nullpointerexception. it was a preview feature then and later became the standard part of the jdk.
