B4J Question Java crash on pi3

[MbedAndroid]

i got 2 pi's running, same program. Pi3 has worked intermitted last month. Sometimes weeks without any problem, last days it's resets when i use B4j. As soon i delete the b4j app the pi is stable. Updated jdk to latest version 152, hardfloat. Setted the speed to 700mhz (very low for a pi3)
Still the issue.
Attached a doc of the stack
Is this somehow a b4j problem?

The java version in this report is: 1.8.0_65-b17

Maybe there are multiple versions of java installed.

the issue was on 1.8.0_65 and also on the newer installed java release152.
it comes and goes.... That gives me a idea of temperature... After setting the clock to 700mhz it stopped after 2 hours.
To be observered..................
