Peter Lawrey’s comment gave the idea of editing
rt.jar. This works. It is also utterly harmless.(changed access modifier code
0x0104to0x0101at the right place inrt.jar/java/lang/Object.class)Similarly, one can construct an
rtplus.jarcontaining just the modified class file and use-Xbootclasspath/p:rtplus.jarto havejavause that version instead. (and yes, EJP, we can’t distribute thatrtplus.jarbut it’s quite easy to generate programmatically)
