It would be helpful to include details of how you're building so people can try and replicate this issue. From the log, it looks like an x86 build. Are you building the whole JDK? My guess would be that JVMSetNativeThreadName should be present in HotSpot and indeed grep confirms this: $ grep -r 'JVMSetNativeThreadName' * make/linux/makefiles/mapfile-vers-debug: JVMSetNativeThreadName; make/linux/makefiles/mapfile-vers-product: JVMSetNativeThreadName; make/solaris/makefiles/mapfile-vers: JVMSetNativeThreadName; src/share/vm/prims/jvm.cpp:JVMENTRY(void, JVMSetNativeThreadName(JNIEnv* env, jobject jthread, jstring name)) src/share/vm/prims/jvm.cpp: JVMWrapper("JVMSetNativeThreadName"); src/share/vm/prims/jvm.h:JVMSetNativeThreadName(JNIEnv *env, jobject jthread, jstring name); It seems to have been introduced in: -- Andrew :) Free Java Software Engineer Red Hat, Inc.
