第一次遇到这种问题，一头雾水。
近期只是在系统里面新增了一个随系统启动的new.jar，放在BOOTCLASSPATH里面。
对比：
1.刷不带new.jar的老固件测试，ok
2.刷带new.jar的debug版本固件测试，ok
3.刷带new.jar的user版本固件测试，不ok
显然，是new.jar在user模式下出了问题。
分析：
debug模式跟user模式的差别？
1.权限不一样，但是不会影响new.jar，所以，排除权限的问题。
2.user和debug模式下，env有差异？实际对比之后发现env是一样的，排除env
3.art odex优化，仔细查看/system/framework/arm里面的oat art文件，结合env里面的jar列表，终于有了重大发现，新增的new.jar并没有对应的boot-xx.oat boot-xx.art文件，看来就是这个原因了。
进一步验证：
各种百度之后，终于看到了有价值的信息，PRODUCT_BOOT_JARS对应的环境变量应该以core-oj开头，而我新增new.jar之后，变成了new.jar开头，因此导致了生成的boot-core-oj.oat有问题，只要访问到这里的内存就会出错，从而挂掉。
正确的环境变量配置：
BOOTCLASSPATH=/system/framework/core-oj.jar:/system/framework/core-libart.jar:/system/framework/conscrypt.j
ar:/system/framework/okhttp.jar:/system/framework/core-junit.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/
framework.jar:/system/framework/telephony-common.jar:/system/framework/voip-common.jar:/system/framework/ims-common.jar:/system/framework/apache
-xml.jar:/system/framework/org.apache.http.legacy.boot.jar:/system/framework/qcom.fmradio.jar:/system/framework/tcmiface.jar:/system/framework/t
elephony-ext.jar:/system/framework/oem-services.jar:/system/framework/new.jar
错误的环境变量配置：
BOOTCLASSPATH=/system/framework/new.jar:/system/framework/core-oj.jar:/system/framework/core-libart.jar:/system/framework/conscrypt.j
ar:/system/framework/okhttp.jar:/system/framework/core-junit.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/
framework.jar:/system/framework/telephony-common.jar:/system/framework/voip-common.jar:/system/framework/ims-common.jar:/system/framework/apache
-xml.jar:/system/framework/org.apache.http.legacy.boot.jar:/system/framework/qcom.fmradio.jar:/system/framework/tcmiface.jar:/system/framework/t
elephony-ext.jar:/system/framework/oem-services.jar
很显然是PRODUCT_BOOT_JARS += new.jar的位置问题。包含PRODUCT_BOOT_JARS += new.jar的mk文件被include太靠前，导致编译之后出现在开头处。参考其他的PRODUCT_BOOT_JARS，挪动位置到其他mk里面，编译system.img验证，out/xx/system/framework/arm/目录下生成对应的oat art文件即可。
同时，在编译阶段增加检验，如果PRODUCT_BOOT_JARS不是core-oj开头，直接报错，停止编译。
