Reset back to the default runtime when updating IntelliJ IDEA to get the latest compatible version of JetBrains Runtime. When using a non-default Java runtime for IntelliJ IDEA, it will not update with the IDE and may not be compatible with the new version. Do not change it unless you were specifically asked to do so by JetBrains support. However, in some cases you may be required to use another Java runtime or a specific version of JetBrains Runtime.Ĭhanging the runtime may cause unexpected problems. It is recommended to run IntelliJ IDEA using JetBrains Runtime, which fixes various known OpenJDK and Oracle JDK bugs, and provides better performance and stability. As a Java application, IntelliJ IDEA includes JetBrains Runtime (based on OpenJDK 11), which is used by default.
