@dapengzhang0 Did you figure out what caused the assertion failure? I am getting it in a completely unrelated scenario (involving jdk11 and sybase's jconn4 driver)

dapengzhang0 commented 5 years ago

@henrik242 I'm not actively working on it, just logged the issue. It might be a bug for certain versions of jdk release.

@henrik242 I have the same issue and we are also using sybase jconn4 driver.. I run into this constantly when debugging in Idea on mac.

I have spent quite some time with SAP support trying to locate the latest jconn4 drivers without any luck. If you have found this or managed to solve the issue then please let me know!

henrik242 commented 5 years ago

@andersaa I worked around it by switching to the jconn3 driver.
