An internal error occurred during: "Requesting Java AST from selection". java.lang.NoSuchMethodError: com.ibm.icu.text.UTF16.isSurrogate(C)Z

Question

I'm using

• eclipse.buildId=4.24.0.I20220607-0700
• java.version=11.0.17.
• BootLoader constants: OS=macosx, ARCH=aarch64, WS=cocoa

Error: An internal error occurred during: "Requesting Java AST from selection". java.lang.NoSuchMethodError: com.ibm.icu.text.UTF16.isSurrogate(C)Z

This error occurred after downloading the Oracle WebLogic Server Tools plugin (17.3.0.201903121357) on eclipse.

From what I've found, it's probably because there are two versions of ICU4J, and the 72v only has this method boolean isSurrogate(int codePoint) and not boolean isSurrogate(char char16).

Does anyone know how to fix this without upgrading eclipse to 4.25? As it seems like 4.24 is the most recent version that supports Java 11.

I've already tried deleting the ICU4J 72 plugin manually but it removes maven from my eclipse.

Answer 1

4.25 and 4.26 both support developing for Java 11, they just have components that require Java 17 to run properly. You can download a compatible JDK from https://adoptium.net/temurin/releases/ .

If there's a newer WebLogic plug-in, you should also get that. Version 17.3.0.201903121357 indicates a build from 2019.

Answer 2

Very frustrating. I'm getting this error in a little box.

"An internal error occurred during: "Requesting Java AST from selection". com.ibm.icu.text.UTF16.isSurrogate(C)Z"

I minimize the error box. It drops to the lower left corner of the screen, and everything seems to work fine. Will research this later.
