isInNativeImageAndIsAtRuntime
public static boolean isInNativeImageAndIsAtRuntime()
Check whether we're running in SubstrateVM native image and also in "runtime" mode. The "runtime" check cannot be a constant, because the static initializer may run early during build timeAs optimization,
RUNNING_IN_SVM
is used to short-circuit on normal JVMs.- Since:
- 2.16
-
isInNativeImage
public static boolean isInNativeImage()
Checks whether we're running in SubstrateVM native image only by the presence of"org.graalvm.nativeimage.imagecode"
system property, regardless of its value (buildtime or runtime). We are irrespective of the build or runtime phase, because native-image can initialize static initializers at build time.- Since:
- 2.16
-
isUnsupportedFeatureError
public static boolean isUnsupportedFeatureError(java.lang.Throwable e)
Check whether the given error is a substratevm UnsupportedFeatureError
-
needsReflectionConfiguration
public static boolean needsReflectionConfiguration(java.lang.Class<?> cl)
Check whether the given class is likely missing reflection configuration (running in native image, and no members visible in reflection).
