Hi all, hi Srikanth, It's not clear for me if JDK-8144185 [1] was backported to 8 and 9 or not, if it's not, given that we, the ASM team, have seen several independent reports of this issue, we think that this issue, which generate invalid class files, is a good candidate for backports. cheers, Rémi [1] https://bugs.openjdk.java.net/browse/JDK-8144185
