从jbpm 6.5更新到7.17时出现的问题：
我经常遇到以下僵局：
os.arch:amd64这是一个已知问题吗？我必须在流程中采用某些方法吗？
我在wildfly 16-> Java 11-> Oracle上运行
我还必须增加“ CORRELATIONPROPERTYINFO.Value”列的列大小，因为它大于255个字符
我添加了一个插入触发器，并将条目存储在单独的表中->以下是示例条目：
“ 6165871：eu.some.company.engine.core.processes.common.findavailability.v1.find：1551899839103：eu.some.company.engine.engine.processes.common.findavailability.v1.alternatives：1551899839989： eu.some.company.engine.core.processes.common.findavailability.v1.alternative：1551899839994“
仅作记录->我还必须更新一个jpa查询：
