构建openjdk9时出错

我刚刚克隆了openjdk9：

> hg clone http://hg.openjdk.java.net/jdk9/dev 9dev
> cd 9dev
> sh get_source.sh
> bash configure
> make

现在，我想构建它，但是在“ make”之后出现此错误：

Compiling 457 files for BUILD_INTERIM_jdk.javadoc
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Compiling 159 files for BUILD_TOOLS_JDK
-Xbootclasspath/p is no longer a supported option.

make[2]: *** Attesa per i processi non terminati....

这是错误的输出：

ERROR: Build failed for target 'default (exploded-image)' in configuration 'linux-x86_64-normal-server-release' (exit code 141)

怎么了 为什么？
