Comparison of Java virtual machines
| JVM | Status | Supported architectures | Supported operating systems | Compilation | Supported class libraries | Supported Java versions | Licence |
|---|---|---|---|---|---|---|---|
| Hotspot | Reference implementation | The free and open-source OpenJDK version supports x86, amd64, and SPARC (running Solaris only).[1]
The IcedTea project has also developed a MIPS port.[2] Oracle's closed-source JDK also supports Itanium.[3] The commercial Java SE Embedded project supports other architectures, including ARM and Power.[4] |
Windows, Linux, MacOS X, and Solaris are officially supported.[5] Ports to BSD[6], Haiku[7], and PowerPC/AIX[8] are in various states of completion. | Interpretation and multiple types of JIT | OpenJDK | All of them | GPL version 2 only for the open-source OpenJDK release. Closed-source EULA for the Oracle JDK release. Pay-per-copy licencing for Java SE Embedded. |
| JamVM[9] | Light footprint | x86, amd64, ARM, MIPS, PowerPC, PowerPC64, SPARC | Linux, MacOS X, FreeBSD, OpenBSD, kFreeBSD, Solaris, OpenSolaris | Interpretation and light JIT | GNU Classpath (and OpenJDK with a patch[10]) | GPL |
