Motivation: Native image compilation is failing without extra flags: ``` Warning: Aborting stand-alone image build. No instances of io.netty.buffer.UnpooledHeapByteBuf are allowed in the image heap as this class should be initialized at image runtime. Object has been initialized by the io.netty.handler.codec.http2.Http2ConnectionHandler class initializer with a trace: at io.netty.buffer.Unpooled.wrappedBuffer(Unpooled.java:157) at io.netty.handler.codec.http2.Http2ConnectionHandler.<clinit>(Http2ConnectionHandler.java:74) . To fix the issue mark io.netty.buffer.UnpooledHeapByteBuf for build-time initialization with --initialize-at-build-time=io.netty.buffer.UnpooledHeapByteBuf or use the the information from the trace to find the culprit and --initialize-at-run-time=<culprit> to prevent its instantiation. Detailed message: Trace: object io.netty.buffer.ReadOnlyByteBuf object io.netty.buffer.UnreleasableByteBuf method io.netty.handler.codec.http2.Http2ConnectionHandler.access$500() Call path from entry point to io.netty.handler.codec.http2.Http2ConnectionHandler.access$500(): at io.netty.handler.codec.http2.Http2ConnectionHandler.access$500(Http2ConnectionHandler.java:66) at io.netty.handler.codec.http2.Http2ConnectionHandler$PrefaceDecoder.readClientPrefaceString(Http2ConnectionHandler.java:299) at io.netty.handler.codec.http2.Http2ConnectionHandler$PrefaceDecoder.decode(Http2ConnectionHandler.java:239) at io.netty.handler.codec.http2.Http2ConnectionHandler.decode(Http2ConnectionHandler.java:438) at io.netty.handler.codec.ByteToMessageDecoder.decodeRemovalReentryProtection(ByteToMessageDecoder.java:505) at io.netty.handler.codec.ByteToMessageDecoder.callDecode(ByteToMessageDecoder.java:444) at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:283) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:374) at io.netty.channel.AbstractChannelHandlerContext.access$600(AbstractChannelHandlerContext.java:56) at io.netty.channel.AbstractChannelHandlerContext$7.run(AbstractChannelHandlerContext.java:365) at com.oracle.svm.core.jdk.RuntimeSupport.executeHooks(RuntimeSupport.java:144) at com.oracle.svm.core.jdk.RuntimeSupport.executeStartupHooks(RuntimeSupport.java:89) at com.oracle.svm.core.JavaMainWrapper.runCore(JavaMainWrapper.java:143) at com.oracle.svm.core.JavaMainWrapper.run(JavaMainWrapper.java:186) at com.oracle.svm.core.code.IsolateEnterStub.JavaMainWrapper_run_5087f5482cc9a6abc971913ece43acb471d2631b(generated:0) ``` Modification: Add `io.netty.handler.codec.http2.Http2ConnectionHandler` for runtime compilation, as the buffer library's `io.netty.buffer.UnpooledHeapByteBuf` is also marked for runtime. Result: Native image compilation works again. |
