Jasypt and Weblogic environment variables - spring

Question

I am using jasypt 1.9.2 to encrypt a password in a property file for my spring REST service. I've added an environment variable to Weblogic via the Server startup arguments text box called APP_ENCRYTPION_PASSWORD, but that environment variable is not getting read by the jasypt. Here is the error:
ERROR o.s.web.servlet.DispatcherServlet - Context initialization failed
java.lang.NullPointerException: null
at org .jasypt.encryption.pbe.config.SimplePBEConfig.getPasswordCharArray(SimplePBEConfig.java:434) ~[jasypt-1.9.2.jar:na]
Here is the Weblogic environment variable logged during when the server starts up:
JAVA_OPTIONS= -Dother.vars=xxx -DAPP_ENCRYPTION_PASSWORD=password -Dmore.vars=yyy
I've traced the jasypt code and it seems jasypt does not parse the environment variables within JAVA_OPTIONS. I know this works for other frameworks like spring since we have other environment variables within JAVA_OPTIONS that spring has no issue reading.
I could add the environment variable to the startup scripts (setEnv.sh I think) for weblogic, but that will add the variable for all managed nodes instead of the one cluster my app is deployed to.
Is there a different way to configure jasypt within spring to get the environment variables within JAVA_OPTIONS?
Here is my spring config:
<bean
class="org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer">
<constructor-arg>
<bean class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
<property name="config">
<bean class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndTripleDES" />
<property name="passwordEnvName" value="APP_ENCRYPTION_PASSWORD" />
</bean>
</property>
</bean>
</constructor-arg>
<property name="location">
<value>application.properties
</value>
</property>
</bean>
My application.properties file contents:
username=someuser
password=ENC(encryptedstring)
UPDATE for clarity:
Adding the environment variable to weblogic via setEnv.sh or Eclipse works just fine. It's only when I use the weblogic console to add the environment variable for a cluster that jasypt fails to parse the value since it is within JAVA_OPTIONS.

You can use passwordSysPropertyName instead of passwordEnvName. This way you can use -DpasswordSysPropertyName="mysecret"
<bean id="environmentVariablesConfiguration"
class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndDES" />
<property name="passwordSysPropertyName" value="APP_ENCRYPTION_PASSWORD" />
</bean>
