TODO
- it seems as an unnecessary overhead to throw and swallow an exception with each such request for upgrade that is supposedly valid and done by a well established client (curl)
- TODO mbabacek1@redhat.com: create an upstream Apache bugzilla if found pertinent

Line 1174 in Http2UpgradeHandler.java:
1156 @Override 1157 public boolean fill(boolean block, byte[] data, int offset, int length) throws IOException { 1158 int len = length; 1159 int pos = offset; 1160 boolean nextReadBlock = block; 1161 int thisRead = 0; 1162 1163 while (len > 0) { 1164 thisRead = socketWrapper.read(nextReadBlock, data, pos, len); 1165 if (thisRead == 0) { 1166 if (nextReadBlock) { 1167 // Should never happen 1168 throw new IllegalStateException(); 1169 } else { 1170 return false; 1171 } 1172 } else if (thisRead == -1) { 1173 if (connectionState.get().isNewStreamAllowed()) { -> 1174 throw new EOFException(); 1175 } else { 1176 return false; 1177 } 1178 } else { 1179 pos += thisRead; 1180 len -= thisRead; 1181 nextReadBlock = true; 1182 } 1183 } 1184 return true; 1185 }
I think I get how is the read block treated, but I don't understand why an exception is needed to control the flow?
