Very simple maven project to reproduce
Since 8.5.51 we cannot precompile jsps. We are using jspc-maven-plugin:
[WARNING] org.apache.jasper.JasperException: javax.el.ELException: Unable to
find ExpressionFactory of type [# Licensed to the Apache Software Foundation

This is the stacktrace:

It can be easily reproduced with a simple Maven project:
<dependencies>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jasper</artifactId>
<version>8.5.53</version>
</dependency>
</dependencies>
<build>
<finalName>tomcat-jasper-compiler</finalName>
<plugins>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-jspc-maven-plugin</artifactId>
<version>9.4.27.v20200227</version>
<executions>
<execution>
<id>jspc</id>
<phase>process-classes</phase>
<goals>
<goal>jspc</goal>
</goals>
</execution>
</executions>
<configuration>
<webAppSourceDirectory>${project.basedir}/src/main/webapp</webAppSourceDirectory>
<sourceVersion>1.8</sourceVersion>
<targetVersion>1.8</targetVersion>
</configuration>
</plugin>
</plugins>
</build>
With a single jsp in it, "mvn clean install" causes the error. Switching jasper
to 8.5.50 solves it. Debugging revealed that the classname for the expression
factory cannot be resolved, instead it tries to load the first comment from
javax.el.ExpressionFactory services file in tomcat-jasper-el-8.5.53.jar:

org.apache.el.ExpressionFactoryImpl
Since this is reproduceable with only one dependency (tomcat-jasper) and a very
minimal setup I don't know what I could change.
Thanks,
Marek
