Spotless: [gradle-plugin]: Latest update (5.5.0) is broken on JDK loom eap builds

[sureshg]

• [x] summary of problem
  This commit is broken on JDK loom EAP builds (java.lang.StringIndexOutOfBoundsException). The plugin was working fine on all JDK eap versions, including project loom . The version format used is,

$ java -version    
openjdk version "16-loom" 2021-03-16
OpenJDK Runtime Environment (build 16-loom+6-105)
OpenJDK 64-Bit Server VM (build 16-loom+6-105, mixed mode, sharing)

Is it possible to handle the EAP version also?

• [x] gradle or maven version
  
  
  
  • 6.7-rc-1
  
  
• [x] spotless version
  
  
  
  • 5.5.0
  
  
• [x] operating system and version
  
  
  
  • Mac OSX (10.13.6)
  
  
• [x] copy-paste your full Spotless configuration block(s), and a link to a public git repo that reproduces the problem if possible
