First I appolgize for potentially mis-classifying the error. Please re-classify to a more specific component if necessary. link is to a .class file for java. When downloaded with Safari or webkit, the file is considered by the java compiler to be a "bad class file". I downloaded the same file with Firefox and the file runs just fine. I did a couple small tests and someone else might be able to interpret the results better than I. I downloaded the file from Firefox (Banker.class) and downloaded the same file from Webkit 528+ (Banker1.class). Then ran in Terminal: #cmp -c Banker.class Banker1.class Output was: Banker.class Banker1.class differ: byte 1, line 1 is 312   276 æ There appears to be no differences if you use the context menu to "save as.." or just click and download to the downloads dir. Eror is the same. The verbose cmp tool gives more specific byte by byte info: #cmp -l Banker.class Banker1.class Output: 1 312 276 2 376 272 3 272 376 4 276 312 5 0 62 8 62 0 10 33 12 11 12 33 13 5 11 14 0 26 15 26 0 16 11 5 17 0 27 18 4 0 19 0 4 20 27 0 21 11 0 22 0 4 23 4 0 24 0 11 25 30 31 26 7 0 27 0 7 28 31 30 29 7 1 30 0 32 31 32 0 32 1 7 33 0 141 34 4 156 35 156 4 36 141 0 37 155 0 38 145 1 39 1 145 40 0 155 41 22 141 42 114 152 43 152 114 44 141 22 45 166 154 46 141 57 47 57 141 48 154 166 49 141 57 50 156 147 51 147 156 52 57 141 53 123 151 54 164 162 55 162 164 56 151 123 57 156 1 58 147 73 59 73 147 60 1 156 61 0 141 62 6 163 63 163 6 64 141 0 65 154 171 66 141 162 67 162 141 68 171 154 69 1 104 70 0 1 71 1 0 72 104 1 73 1 74 74 0 6 75 6 0 76 74 1 77 151 164 78 156 151 79 151 156 80 164 151 81 76 3 82 1 0 83 0 1 84 3 76 85 50 1 86 51 126 87 126 51 88 1 50 89 0 157 90 4 103 91 103 4 92 157 0 93 144 0 94 145 1 95 1 145 96 0 144 97 17 156 98 114 151 99 151 114 100 156 17 101 145 155 102 116 165 103 165 116 104 155 145 105 142 124 106 145 162 107 162 145 108 124 142 109 141 145 110 142 154 111 154 142 112 145 141 113 1 50 114 0 26 115 26 0 116 50 1 117 114 166 118 152 141 119 141 152 120 166 114 122 57 154 123 154 57 125 156 123 126 147 57 127 57 147 128 123 156 129 164 156 130 162 151 131 151 162 132 156 164 133 147 51 134 73 104 135 104 73 136 51 147 137 126 7 138 1 0 139 0 1 140 7 126 141 147 116 142 145 164 143 164 145 144 116 147 145 141 1 146 155 145 147 145 155 148 1 141 149 0 51 150 24 50 151 50 24 152 51 0 153 114 166 154 152 141 155 141 152 156 166 114 158 57 154 159 154 57 161 156 123 162 147 57 163 57 147 164 123 156 165 164 156 166 162 151 167 151 162 168 156 164 169 147 0 170 73 1 171 1 73 172 0 147 173 11 164 174 147 145 175 145 147 176 164 11 177 123 141 178 141 154 179 154 141 180 141 123 181 162 0 182 171 1 183 1 171 184 0 162 185 3 104 186 50 51 187 51 50 188 104 3 189 1 164 190 0 10 191 10 0 192 164 1 193 157 162 194 123 164 195 164 123 196 162 157 197 151 1 198 156 147 199 147 156 200 1 151 201 0 157 202 12 123 203 123 12 204 157 0 205 165 145 206 162 143 207 143 162 208 145 165 209 106 145 210 151 154 211 154 151 212 145 106 213 1 102 214 0 13 215 13 0 216 102 1 217 141 145 218 156 153 219 153 156 220 145 141 221 162 141 222 56 152 223 152 56 224 141 162 225 166 0 226 141 14 227 14 141 228 0 166 229 12 14 230 0 13 231 13 0 232 14 12 233 0 7 234 6 0 235 0 6 236 7 0 237 14 0 238 0 10 239 10 0 240 0 14 241 11 6 242 1 0 243 0 1 244 6 11 245 102 153 246 141 156 247 156 141 248 153 102 249 145 0 250 162 1 251 1 162 252 0 145 253 20 166 254 152 141 255 141 152 256 166 20 258 57 154 259 154 57 261 156 117 262 147 57 263 57 147 264 117 156 265 142 143 266 152 145 267 145 152 268 143 142 269 164 0 270 4 40 271 40 4 272 0 164 273 4 0 274 0 5 275 5 0 276 0 4 278 0 2 279 2 0 281 2 0 282 0 6 283 6 0 284 0 2 285 7 0 288 0 7 289 2 0 290 0 10 291 10 0 292 0 2 293 11 0 296 0 11 297 5 0 298 0 1 299 1 0 300 0 5 301 12 0 302 0 13 303 13 0 304 0 12 305 1 0 306 0 14 307 14 0 308 0 1 310 0 35 311 35 0 313 1 0 314 0 1 315 1 0 316 0 1 317 0 52 318 0 5 319 5 0 320 52 0 321 267 261 322 0 1 323 1 0 324 261 267 325 0 1 328 1 0 330 15 0 331 0 15 333 0 1 334 6 0 335 0 6 336 1 0 337 0 4 340 4 0 341 0 12 342 1 0 343 0 1 344 12 0 345 0 1 346 16 0 347 0 16 348 1 0 350 14 0 351 0 14 353 0 3 354 63 0 355 0 63 356 3 0 358 4 0 359 0 4 361 0 267 362 17 52 363 52 17 364 267 0 365 0 53 366 1 52 367 52 1 368 53 0 369 265 52 370 0 2 371 2 0 372 52 265 373 50 3 374 265 0 375 0 265 376 3 50 377 261 0 380 0 261 381 1 0 382 0 15 383 15 0 384 0 1 386 0 22 387 22 0 389 4 0 392 0 4 393 6 0 394 0 4 395 4 0 396 0 6 397 7 0 398 0 11 399 11 0 400 0 7 401 10 0 402 0 16 403 16 0 404 0 10 405 11 0 406 0 1 407 1 0 408 0 11 409 17 0 410 0 20 411 20 0 412 0 17 413 1 0 414 0 14 415 14 0 416 0 1 418 0 35 419 35 0 421 1 0 422 0 1 423 1 0 424 0 1 425 0 52 426 0 5 427 5 0 428 52 0 429 264 260 430 0 2 431 2 0 432 260 264 433 0 1 436 1 0 438 15 0 439 0 15 441 0 1 442 6 0 443 0 6 444 1 0 445 0 15 448 15 0 449 0 21 450 1 0 451 0 1 452 21 0 453 0 1 454 22 0 455 0 22 456 1 0 458 14 0 459 0 14 461 0 2 462 35 0 463 0 35 464 2 0 466 1 0 467 0 1 469 0 264 470 5 52 471 52 5 472 264 0 474 3 257 475 257 3 478 0 1 479 1 0 481 15 0 484 0 15 485 6 0 486 0 1 487 1 0 488 0 6 489 0 4 490 0 22 491 22 0 492 4 0 493 1 0 494 0 23 495 23 0 496 0 1 497 20 0 500 0 20 501 1 0 502 0 24 503 24 0 504 0 1 506 0 2 507 2 0 509 25 0
