错误一

根据提示，需要修改src/hotspot/share/runtime/arguments.cpp文件的源码： 将第1461行的常量从DEFAULT_VENDOR_URL_BUG更改为0 更改前：

1461 if (old_java_vendor_url_bug != DEFAULT_VENDOR_URL_BUG) {
更改后：

1461 if (old_java_vendor_url_bug != 0) {

错误二

更改源码之后，重新make clean，然后make
$ make clean

... ...
$  make

根据，提示，我们需要修改src/hotspot/share/runtime/sharedRuntime.cpp这个文件的源码。 更改前：

2798       buffer.insts()->initialize_shared_locs((relocInfo*)locs_buf, sizeof(locs_buf) / sizeof(relocInfo));
更改后：

2798       buffer.insts()->initialize_shared_locs((relocInfo*)locs_buf, (sizeof(locs_buf)) / (sizeof(relocInfo)));
你没看错。。就是增加了两个括号而已，但是就是这么神奇，不加就报错，加了就不报错

错误三

重新make clean后，再次make，这时候出现了第三个编译错误。。。

$ make clean

$ make

=== Output from failing command(s) repeated here ===

从错误信息里面可以看出，我们这里需要修改src/java.desktop/macosx/native/libawt_lwawt/awt/CSystemColors.m这个文件，修改方式和第2个错误基本相同，也是加括号=_=

修改前：

134     if (colorIndex < (useAppleColor) ? sun_lwawt_macosx_LWCToolkit_NUM_APPLE_COLORS : java_awt_SystemColor_NUM_COLORS) {
修改后：

134     if (colorIndex < ((useAppleColor) ? sun_lwawt_macosx_LWCToolkit_NUM_APPLE_COLORS : java_awt_SystemColor_NUM_COLORS)) {
基本没啥差别，就是加了个括号。

这时再次make，还会出现一个错误

可以看到，这里需要修改src/java.desktop/macosx/native/libjsound/PLATFORM_API_MacOSX_MidiUtils.c文件的4个地方。但是修改方式是统一的，都是将括号里的内容（MIDIClientRef,MIDIPortRef,MIDIEndpointRef）修改为unsigned long。

修改前：

263 static MIDIClientRef client = (MIDIClientRef) NULL;
264 static MIDIPortRef inPort = (MIDIPortRef) NULL;
265 static MIDIPortRef outPort = (MIDIPortRef) NULL;

471 MIDIEndpointRef endpoint = (MIDIEndpointRef) NULL;

修改后：

265 static MIDIPortRef outPort = (unsigned long) NULL;

471 MIDIEndpointRef endpoint = (unsigned long) NULL;

把用到的几处先注释掉 assert
