Question

我正在上一门课程，其中使用Maven执行作业，并且项目随附了.pom文件。分配需要大约1.5gb的内存来处理。但是，当提供超过1GB的内存时，我会收到以下输出：

[WARNING] Corrupted STDOUT by directly writing to native stream in forked JVM 1
ExecutionException The forked VM terminated without properly saying goodbye. VM 
crash or System.exit called?
Error occurred in starting fork, check output in log

转储显示为：

Corrupted STDOUT by directly writing to native stream in forked JVM 1. Stream 
'Error occurred during initialization of VM'.
java.lang.IllegalArgumentException: Stream stdin corrupted. Expected comma 
after third character in command 'Error occurred during initialization of VM'.

有问题的区块是：

<plugin>
                <!-- executes test with -Xmx option -->
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.0</version>
                <configuration>
                    <forkCount>4</forkCount>
                    <reuseForks>true</reuseForks>
                    <argLine>-Xmx2048m</argLine>
                    <useSystemClassLoader>true</useSystemClassLoader>
                    <testFailureIgnore>true</testFailureIgnore>
                </configuration>
            </plugin>

在-Xmx设置为大于1g / 1024m的地方，我遇到了上述问题。

-Xmx设置为超过1g时，分叉的VM终止而未正确说再见
