Class JVMCIVersionCheck

java.lang.Object

org.graalvm.compiler.hotspot.JVMCIVersionCheck

public final class JVMCIVersionCheck
extends Object

Mechanism for checking that the current Java runtime environment supports the minimum JVMCI API required by Graal. The JVMCI_VERSION_CHECK environment variable can be used to ignore a failed check (JVMCI_VERSION_CHECK=ignore) or print a warning ( JVMCI_VERSION_CHECK=warn) and continue. Otherwise, a failed check results in an InternalError being raised or, if called from JVMCIVersionCheck.main(String[]), the VM exiting with a result code of -1 This class only depends on the JDK so that it can be used without building Graal.
