  • 由于java.util.regex行重复太多次，堆栈跟踪不包括问题的根源
  • 在Windchill/codebase/WEB-INF/log4jMethodServer.properties 的登录下方启用：
log4j.logger.wt.adapter.verbose=全部
log4j.logger.com.ptc.core.adapter.server.impl.SearchObjectsWebjectDelegate=ALL
log4j.logger.com.ptc.windchill.enterprise.search.server.WhereClauseHandler=ALL
  • 启用日志记录后，在StackOverflowError之前报告了此行：
