how to modify type of "$jacocoInit"

[jun yin]

I want to modify $jacocoInit from boolean[] to int[]. I changed the "[Z" to "[I", yet I calls these exceptions:

Exception in thread "main" java.lang.BootstrapMethodError: bootstrap method initialization exception
at java.base/java.lang.invoke.BootstrapMethodInvoker.invoke(BootstrapMethodInvoker.java:188)

Caused by: java.lang.ClassCastException: class [Z cannot be cast to class [I ([Z and [I are in module java.base of loader 'bootstrap')
at com.example.demo.SpringbootDemoApplication.$jacocoInitt(SpringbootDemoApplication.java)
at java.base/java.lang.invoke.BootstrapMethodInvoker.invoke(BootstrapMethodInvoker.java:90)
... 4 more

what should I do next, thanks.

Hi,

JaCoCo uses boolean arrays to store probes. If you want to change that data type you basically have to change every aspect of JaCoCo: instrumentation, execution data handling, exec file format and remote protocols, analysis etc.

Thanks a lot. I found out I forgot to modify probes in ExecutionData. It is too confuse to make such a mistake.
