Add -Xalwaysclassgc to Test5102804

[annaibm]

• Updated the run directive with -Xalwaysclassgc jvm option
• This is a temporary workaround and should be reviewed once the root cause is identified.

I'm not sure this is a solution, just a temporary workaround, which we should call out in the commit description.
@dmitripivkine are you still investigating why this option is needed?

Also, this change should start at the openjdk head stream (openj9-openjdk-jdk) and then be backported to 23, 21, 17, and then 11. Unless for some reason it only fails on 11?

Well, I have a plan to find out exact scenario. However I don't think there is something wrong with handling. This is combination class unloading - > clearing Weak Ref. OpenJ9 does not do class unloading every time. It does it for aggressive GC to prevent OOM but it is too late to process Weak Ref. If you need this test pass without pushing class unloading every single Global GC an alternative can be to have another run of aggressive Global GC. I am not sure it is necessary.

Based on the current results , The test: java/beans/Introspector/Test5102804.java -, seems to fail in both version 8 and 11, but not in versions 17, 21, or 23.
