I hit this assert when running my EA VM with CTW

#  Internal Error (src/share/vm/utilities/growableArray.hpp:173), pid=8075, tid=2
#  Error: assert(0 <= i && i < _len,"illegal index")

CodeCache is full (without EA it is full few methods further) as result
the index to growable array is -2:

address methodOopDesc::make_adapters(methodHandle mh, TRAPS) {
...
  AdapterHandlerEntry* adapter = AdapterHandlerLibrary::get_adapter(mh);
  if (adapter == NULL ) {
    THROW_0(vmSymbols::java_lang_OutOfMemoryError());
  }


class AdapterHandlerLibrary: public AllStatic {
  static GrowableArray<AdapterHandlerEntry*> * _handlers; // the corresponding handlers
...
  static AdapterHandlerEntry* get_entry( int index ) { return _handlers->at(index); }
  static AdapterHandlerEntry* get_adapter(methodHandle method)  { return get_entry(get_create_adapter_index(method)); }


int AdapterHandlerLibrary::get_create_adapter_index(methodHandle method) {
...
    B = BufferBlob::create(AdapterHandlerEntry::name, &buffer);
    if (B == NULL)  return -2;          // Out of CodeCache space

N/A

There are few problems here:

0. AdapterHandlerLibrary::get_create_adapter_index() should return
   0 (instead of -2) when CodeCache is full. The NULL adaper value 
   is stored in the first array element AdapterHandlerLibrary::_handlers[0].
1. methodOopDesc::make_adapters() doesn't check that compilation was disabled.
   It is only check that VM runs with -Xint option.
2. VM doesn't exit immediately if CodeCache is full in methods
   AdapterHandlerLibrary::get_create_adapter_index() and turn_off_compilser()
   when VM runs with -XX:+CompileTheWorld or -XX:+ExitOnFullCodeCache.
