Class ICU4JFeature

java.lang.Object

com.oracle.svm.thirdparty.ICU4JFeature

All Implemented Interfaces:

org.graalvm.nativeimage.hosted.Feature

public final class ICU4JFeature
extends Object
implements org.graalvm.nativeimage.hosted.Feature

ICU4JFeature enables ICU4J library ("http://site.icu-project.org/" to be used in SVM.

The main obstacle in using the ICU4J library as is was that the library relies on class loader to fetch localization data from resource files included in the ICU4J jar archive. This feature is not supported by SVM, so the next option was to read the resource files from the file system. The following code addresses several issues that occurred when specifying com.ibm.icu.impl.ICUBinary.dataPath system property in runtime (standard ICU4J feature).
