RFR: 8264940: java/lang/invoke/6998541/Test6998541.java failed "guarantee(ik->is_initialized()) failed: java/lang/Byte$ByteCache must be initialized"

[Wang Huang]

*  The main reason is that in this situation the `BoxCache` is not initialized before `uncommon_trap`.
*  `java.lang.Byte$ByteCache` is loaded without initializing here 
* I think that all `*Cache` classes should be loaded in this situation.
