Bad assumption on static initializers access flags

[samczsun]

The JVM ignores access flags for <clinit>, and assumes it to only have ACC_STATIC (or ACC_STATIC | ACC_STRICT for Java 8+)

.version 49 0 
.class public final a
.super java/lang/Object 

.method native abstract <clinit> : ()V
    .code stack 10 locals 10
        return
    .end code
.end method

.end class

Edit: Just noticed you already wrote code to handle this JVM quirk. I guess you just forgot to clear the flags
