Download BlueJ Portable 3.1.7 Dev Test 1 (9.56MB download / 13.0MB installed)
Note: All previous versions of BlueJ Portable are now considered obsolete. gluxon has created a portable (and much more secure) version of the OpenJDK, available here. I have removed the embedded versions of the OpenJDK from my build and thus, rely upon his build instead. Please remove all previous versions before updating, and note that the dedicated OpenJDK 7 build is now obsolete and will not be updated further.
