Description
ADDITIONAL SYSTEM INFORMATION :
Linux and Win10
JDK: 11,12,14
A DESCRIPTION OF THE PROBLEM :
javac -h "forgets" to include the magic 00024 before the inner class as passed arg
The important bit is the second 00024 in the method name Java_p_A_00024B_call__Lp_A_00024B_2.
At runtime the resolver looks only for Java_p_A_00024B_call__Lp_A_00024B_2 and not for Java_p_A_00024B_call__Lp_A_B_2 so accessing b.call(b) will result in an UNsatisfiedLinkError.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
execute: javac A.java -h .
