Deprecated Methods

Method	Description
org.graalvm.nativeimage.hosted.RuntimeReflection.register(boolean, boolean, Field...)	Use RuntimeReflection.register(Field...) instead. Parameters finalIsWritable and allowUnsafeAccess no longer serve a purpose.
org.graalvm.nativeimage.hosted.RuntimeReflection.register(boolean, Field...)	Use RuntimeReflection.register(Field...) instead. Parameter finalIsWritable no longer serves a purpose.
org.graalvm.nativeimage.hosted.RuntimeSerialization.registerWithTargetConstructorClass(Class<?>, Class<?>)	Use RuntimeSerialization.register(Class[]) instead. All possible custom constructors will be registered automatically.
org.graalvm.nativeimage.Threading.registerRecurringCallback(long, TimeUnit, Threading.RecurringCallback)	in 25.1 without replacement. This method is inherently unsafe as it can interfere with other code.
org.graalvm.options.OptionType.getDefaultValue()
org.graalvm.options.OptionValues.set(OptionKey<T>, T)	OptionValues should be read-only. If the value of an option needs to be altered after options are set, then the new value should be stored in the language's context or instrument fields and read from there.
org.graalvm.polyglot.Context.Builder.allowHostAccess(boolean)	use Context.Builder.allowHostAccess(HostAccess) or Context.Builder.allowHostClassLookup(Predicate) instead.
org.graalvm.polyglot.Context.Builder.allowIO(boolean)	If the value was previously true pass IOAccess.ALL, otherwise pass IOAccess.NONE.
org.graalvm.polyglot.Context.Builder.fileSystem(FileSystem)	If a file system was previously set use allowIO(IOAccess.newBuilder().fileSystem(fileSystem).build()).
org.graalvm.polyglot.Context.Builder.hostClassFilter(Predicate<String>)	use Context.Builder.allowHostClassLookup(Predicate) instead.
org.graalvm.polyglot.io.FileSystem.allowInternalResourceAccess(FileSystem)	Use FileSystem.allowInternalResources(FileSystem) instead when migrating code that only reads internal resources. The replacement exposes internal resources and language homes through a read-only view. Code that needs mutable files based on internal resources should copy the resources to an application-controlled location, for example with Engine.copyResources(Path, String...), and expose that location through its configured fileSystem.
org.graalvm.polyglot.io.FileSystem.allowLanguageHomeAccess(FileSystem)	Use FileSystem.allowInternalResources(FileSystem) instead to expose language homes and other internal resources through a read-only view.
org.graalvm.polyglot.Source.getInputStream()	use Source.getReader(), Source.getCharacters() or Source.getBytes() instead. The implementation is inefficient and can not distinguish byte and character based sources.
org.graalvm.polyglot.SourceSection.getCode()	use SourceSection.getCharacters() instead.
org.graalvm.word.WordBase.equals(Object)

Deprecated Constructors

Constructor	Description
org.graalvm.options.OptionType(String, T, Function<String, T>)	Use OptionType(String, Function)
org.graalvm.options.OptionType(String, T, Function<String, T>, Consumer<T>)	Use OptionType(String, Function, Consumer)
