When I add option:

```gradle
-verbose:class

```

either to `org.gradle.jvmargs` or to GRADLE\_OPTS, the following exception is thrown:

I’ve managed to find a workaround:  
0. do not use daemon

1. remove all `org.gradle.jvmargs` and `GRADLE_OPTS` options
2. add `-verbose:class` to the last line in gradlew
