PMD Plugin runtime exception error as net.sourceforge.pmd.PMDException: Error while parsing

先从 pmd-eclipse.log 和第 11848 行的 JavaParser 失败开始，然后使用报告中的 PMD Eclipse Plugin 和 Eclipse 版本复现 ${ 情况。确定输入是否为有效的 Java，以及 PMD 是否应提供更清晰的解析结果；当报告的情况得到处理，或所需的源代码修正已记录时，即视为完成。

Eclipse IDE for Enterprise Java Developers Version: 2022-06 (4.24.0) Build id: 20220609-1112
pmd-eclipse-plugin version: 4.40.0.v20221029-0812-r

The following line in Java code causing ERROR n.s.p.e.runtime.cmd.BaseVisitor - Runtime exception visiting and net.sourceforge.pmd.lang.java.ast.ParseException

${CLASS:emxContextUtil}.mqlNotice(context, returnMessage);

In my java code i had used ${ at many places due to this I am getting run time exception

pmd-eclipse.log:
