Recommended Java VM for PDFreactor: OpenJDK 21 Minimum Java Versions Supported by the PDFreactor Library: OpenJDK 17 OpenJDK 9* Oracle JVM 8* *Java versions before 17 are subject to the following limitations: The default JavaScript engine 'GraalJS' is not supported. (The legacy engine 'Rhino' is.) Support for emojis is limited. Support for complex scripts, like Khmer, is severely limited. Java 8 does not support certain variants of OpenType fonts (OTF). This affects the included default CJK font collection (Noto CJK). Complex text rendering is slow in Java 12 and older. Note: Support for Java versions 8 to 16 is deprecated for removal in Q4 2025. Future versions of PDFreactor will require Java 17+. The latest updates should be installed. We have customers successfully using the product in other OpenJDK, Oracle or IBM JVMs, but we don't officially test on those platforms. Besides the Reference Implementation of OpenJDK we also test Eclipse Temurin, which we also package with PDFreactor. Other OpenJDK distributions, like Amazon Corretto, are not tested, but are used by customers without issues. For best performance and text layout results we highly recommend using the latest version of Java. Note: When using the PDFreactor Java Library with Java 22 or newer we recommend setting the following system property to avoid potential crashes due to a bug in that versions of Java: Call System.setProperty("sun.font.layout.ffm", "false"); before PDFreactor or the GlyphVector class is used or use the VM parameter -Dsun.font.layout.ffm=false.
