there should be a log written in the java install whenever the JVM crashes
the most common reason for this is a video driver incompatibility with the JDK - the easiest thing to do now is make sure you have the latest video drivers
if you do, then we need to find the jvm crash log and see what it says
I can't seem to get a log.
I also tried adding
both to sqldeveloper.conf and product.conf, but no log file is written (the directory is writable).
Any hints how to get a log?
I'm running this on a virtual machine to which I connect using VMware Horizon Client, if that makes any difference.
Other Java apps like Eclipse and SoapUI work fine on that machine.
I found another instance of this not on classpath error reported against 4.0.2:
but in 4.0.2 the location of the jar file containing that class is sqldeveloper\jlib whereas in 4.1.5 it is sqldeveloper\modules\oracle.bali.jewt. If you migrated user settings from a SQLDeveloper install of 4.0.3 or earlier, you could try renaming the
C:\Users\<yourUserid>\AppData\Roaming\SQL Developer\system220.127.116.11.78 folder, then restart SQLDeveloper without doing the settings migration to see if that helps.
