tomcat jvm arguments lost-CodePudding

I want to run tomcat with a javaagent.

setenv.sh:

export JAVA_HOME=/home/ggfan/1-install/java/jdk1.8.0_271
export CATALINA_OPTS="${CATALINA_OPTS} -javaagent:/home/ggfan/2-work/centuari-space/jdbc-leak-detector/target/jdbcld.jar=/home/ggfan/3-tmp/logs/jdbcld,INFO,org.apache.commons.dbcp.PoolingDataSource\$PoolGuardConnectionWrapper"

call startup.sh, seems tomcat picked it correctly:

[ggfan@localhost bin]$ ./startup.sh 
Using CATALINA_BASE:   /home/ggfan/1-install/apache-tomcat-8.5.64
Using CATALINA_HOME:   /home/ggfan/1-install/apache-tomcat-8.5.64
Using CATALINA_TMPDIR: /home/ggfan/1-install/apache-tomcat-8.5.64/temp
Using JRE_HOME:        /home/ggfan/1-install/java/jdk1.8.0_271
Using CLASSPATH:       /home/ggfan/1-install/apache-tomcat-8.5.64/bin/bootstrap.jar:/home/ggfan/1-install/apache-tomcat-8.5.64/bin/tomcat-juli.jar
Using CATALINA_OPTS:    -javaagent:/home/ggfan/2-work/centuari-space/jdbc-leak-detector/target/jdbcld.jar=/home/ggfan/3-tmp/logs/jdbcld,INFO,org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper
Tomcat started.

however, from tomcat log:

24-Sep-2021 15:45:04.437 信息 [main] org.apache.catalina.startup.VersionLoggerListener.log 命令行参数：       -javaagent:/home/ggfan/2-work/centuari-space/jdbc-leak-detector/target/jdbcld.jar=/home/ggfan/3-tmp/logs/jdbcld,INFO,org.apache.commons.dbcp.PoolingDataSource

inner class name after '$' sign get lost and the real argument received by my javaagent is the incomplete one.

what is wrong?

I am running with tomcat Apache Tomcat/8.5.64 on fedora 31

CodePudding user response：

In order to split CATALINA_OPTS into words an pass them as arguments to java, the catalina.sh script uses eval:

eval exec "\"$_RUNJAVA\"" "\"$CATALINA_LOGGING_CONFIG\"" $LOGGING_MANAGER "$JAVA_OPTS" "$CATALINA_OPTS" \
...

this obviously performs variable expansion on $PoolGuardConnectionWrapper. To prevent this escape the dollar sign twice:

export CATALINA_OPTS="${CATALINA_OPTS} ...PoolingDataSource\\\$PoolGuardConnectionWrapper"
