Fixing the Loading each jar in <APIM_HOME>/lib and plugins directory during the cipher tool execution

[nadeepoornima]

Description

Based on our cipher tool script, it loads each jar within the following two locations to find "org.wso2.ciphertool.CipherTool" runtime.

<APIM_HOME>/lib/.jar
<APIM_HOME>/repository/components/plugins/.jar
Both directories contain 756 jars, and based on the logic below, each jar is loaded.

# update classpath
CARBON_CLASSPATH=""
for f in "$CARBON_HOME"/lib/*.jar
do
  CARBON_CLASSPATH=$CARBON_CLASSPATH:$f
done
for h in "$CARBON_HOME"/repository/components/plugins/*.jar
do
  CARBON_CLASSPATH=$CARBON_CLASSPATH:$h
done
CARBON_CLASSPATH=$CARBON_CLASSPATH:$CLASSPATH

Therefore, when executing the below command, the customer observed the "Argument list too long" error.

Command:

$JAVA_HOME/bin/java -Dcarbon.home="$CARBON_HOME" -Dcarbon.config.dir.path="$CARBON_HOME"/repository/conf -classpath "$CARBON_CLASSPATH" org.wso2.ciphertool.CipherTool $*

• Error

760
/******/wso2am-4.2.0/bin/ciphertool.sh: line 127: //bin/java: Argument list too long
761
Cleaning up project directory and file based variables
00:00
762
ERROR: Job failed: exit status 1

• Reason
  The "CARBON_CLASSPATH" variable value becomes too long because we are appending each jar.

• Solution

# Update classpath using folder-based approach
CARBON_CLASSPATH="$CARBON_HOME/lib/*:$CARBON_HOME/repository/components/plugins/*:$CLASSPATH"

Steps to Reproduce

Perform cipher encryption in a VM with limited processing capability to handle arguments."
