[ascrutae]

能否提供一个小的demo，帮助本地复现呢? @jaketyao

[wu-sheng]

@jaketyao 这是一个很隐藏的问题，而且和drools的框架代码，使用了asm有关，为了准确定位问题，最好能够提供demo程序用于复现问题。以及com.xu.drools.Rule_22146222303DefaultConsequenceInvoker对应的rule的内容。

[wu-sheng]

@jaketyao I have post the issue to byte-buddy(@raphw) for some clues, let's see what happened.

[wu-sheng]

@jaketyao #706 helps to solve this by skipping the can't resolved type.
