How to find the cause of a OutOfMemoryError in OH2?

I just got another memory leak and a java… file has been created.
So what to do with it?
for me it looks like crap :wink:

JAVA PROFILE 1.0.1^@^@^@^@^D^@^@^Af¦/e^Z^A^@^@^@^@^@^@^@-`I<83>^X(II)Ljava/time/temporal/TemporalAdjuster;^A^@^@^

EDIT:
Checked with Eclipse MAT:

But how to proceed from here?
