Example failure:
Test case:
FILTER_ARGUMENTS
               filterArgsPos => 1
        filtersArgsArrayLength => 2
                    mtTarget => (short,byte,byte,boolean,short,double,boolean,long,short,char,int,char,int,double,short,boolean,float,Object,long,boolean,double,short,int,char,long,long,boolean)char
                    mtFilter => (short,byte)short

Output:
Method type: ()Object
LambdaForm: identity_L=Lambda(a0:L/SpeciesData<L>)=>{
    t1:L=Species_L.argL0(a0:L);t1:L}

Use java/lang/invoke/LFCaching/LFGarbageCollectedTest.java after JDK-8067344 to reproduce. It intermittently fails on identity_L LambdaForm, though requested LambdaForm is different.
