We recently upgraded to V7R5 (IBMi) and applied the latest Java Group PTFs - Level 15 as part of that upgrade.. During testing, we discovered that anything using Java 11 would fail to start due to not being able to create a JVM. After opening a ticket with IBM - they acknowledged that this is currently a "known problem" and supplied a TEST PTF that resolved the issue . They also pointed us to this KB doc outlining the problem including a potential workaround as well.
IBM i Java Development Kit 11 64 bit VMs Fail with UnsatisfiedLinkError After IBM i Java Group PTF Apply
This issue impacts 7.4 and 7.5 Java 11 (64 bit) ONLY for Groups 28 and 15 respectively.
My suggestion is that if you are currently using or have JAVA 11 installed on a V7R4 or V7R5 and are planning to apply the latest GROUP PTFs for that release, read the above KB doc to avoid any disruption to your applications/processes.
