我想在Bluemix下部署和运行一个独立的Java应用程序，该应用程序已在IBM Java 7 JVM下本地配置和测试。在本地，可执行过程在使用命令开始时工作正常：
java -jar myjar.jar
Java jarfile已经包含由MAVEN构建构建的默认META-INF / MANIFEST.MF文件中指定的Class-Path和Main-Class。
使用以下命令部署映像：
cf push myapp1 -p ./target/ibm-myapp-1.0-SNAPSHOT-jar-with-dependencies.jar -b java_buildpack
推送阶段的Bluemix Cloud Foundry为OpenJDK版本8安装运行时。在Bluemix控制台，我得到以下日志消息，没有任何进一步的调试细节，请参阅log ::

如何在Java环境中调试和圈出根错误或如何在应用程序代码中找到错误？

按照我在此处找到的提示[https://support.run.pivotal.io/entries/80755985-How-do-I-size-my-Java-or-JVM-based-applications-] 我在添加到push命令的cloud foundry -m（memory）参数中做了几处调整，该参数自动配置Java堆大小参数（-Xmx）和其他内存相关参数。目前的设置是-m 3G。
日志也引发了关于＆＃34; CRASHED＆＃34;退出状态为127，这可能指向端口级别的问题。我尝试读取环境变量PORT，VCAP_PORT和VCAP_APP_PORT以识别活动端口号。他们都没有改变错误代码。
此外，我已将OpenJDK JVM降级到1.7版，以使用我本地构建环境的相同Java版本。
请参阅下面的日志，到目前为止，添加了最新更改后，错误情况没有变化：
