version 1.1.0 IntelliJ (Community 2019.2) java.lang.IllegalStateException: TextAttributeKey(name:'SIDDHI_COMMA_TOKEN', fallbackAttributeKey:'DEFAULT_COMMA') was already registered

[jing-zhou]

Description:

I am using IntelliJ (Community 2019.2) for the development of siddhi scripts.
I installed the siddhi plugin(1.1.0) as per instruction.
I have the following problem every-time I turn on the IntelliJ and click on a siddhi file (see the snap shot below).

I click on the 'Clear all' button, the error disappears until the next time I turn on IntelliJ and open a siddhi file.
the detailed information reads as below

java.lang.IllegalStateException: TextAttributeKey(name:'SIDDHI_COMMA_TOKEN', fallbackAttributeKey:'DEFAULT_COMMA')  was already registered with the other fallback attribute key: DEFAULT_SEMICOLON
