JVMTI spec for InterruptThread says:

jvmtiError
InterruptThread(jvmtiEnv* env,
             jthread thread)

...
+------------------------------+-------------------------------------------------+
| Error | Description |
+------------------------------+-------------------------------------------------+
| JVMTI_ERROR_THREAD_NOT_ALIVE | thread is not live (has not been started or is |
| | now dead). |
+------------------------------+-------------------------------------------------+

But RI returns error code JVMTI_ERROR_INVALID_THREAD instead of
JVMTI_ERROR_THREAD_NOT_ALIVE.

To reproduce this bug please run on Solaris the following sh script
(do not forget to change JDK_PATH var):

---- File: runme.sh ---------------------------------------------------
JDK_PATH="/java/re/jdk/1.5.0/latest/binaries/solaris-sparc"

JVMTI_H_PATH="${JDK_PATH}/include"

     jvmtiError err;
     jint res;

     res = (*jvm)->GetEnv(jvm, (void **) &jvmti,
           JVMTI_VERSION_1_0);

     if (res != JNI_OK || jvmti == NULL) {
         return JNI_ERR;
     }
     memset(&capa, 0, sizeof(jvmtiCapabilities));
     capa.can_signal_thread = 1;

     err = (*jvmti)->AddCapabilities(jvmti, &capa);
     if (err != JVMTI_ERROR_NONE && err != JVMTI_ERROR_NOT_AVAILABLE) {
         return JNI_ERR;
     }

     return JNI_OK;
}

void describe(jvmtiError err) {
     jvmtiError err0;
     char *descr;
     err0 = (*jvmti)->GetErrorName(jvmti, err, &descr);
     if (err0 == JVMTI_ERROR_NONE) {
         printf(descr);
     } else {
         printf("error [%d]", err);
     }
}

JNIEXPORT void JNICALL

     if (err != JVMTI_ERROR_THREAD_NOT_ALIVE) {
         printf("(InterruptThread) Error expected: ");
         describe(JVMTI_ERROR_THREAD_NOT_ALIVE);
         printf(",\n got: ");
         describe(err);
         printf("\n");
     }
}
