Guntram Blohm updated NETBEANS-6001:
------------------------------------
Description:
When editing a YAML file, if there is a syntax error, netbeans eats up memory
until it reaches 100% of what it's assigned, at which point garbage collection
will use all CPU resources and netbeans becomes unresponsive.
To reproduce:
Create a new empty YAML file in any project
Enter the following text into the file:
{{some key:}}
{{ some value: "this is the value"}}
At this point, watch the widget that shows Netbeans' memory consumption, it
increases rapidly, until it reaches 100%. At this point, Java spends 99% of its
time in garbage collection, Netbeans becomes unresponsive (and if the Java
parameters permit using all cores, the system becomes sluggish as well).
Closing/correcting the yaml file at that point doesn't help.
I attached JProfiler to the JVM that was running netbeans and could confirm the
memory usage increase starting right after entering the invalid yaml. Taking a
heap dump showed 56 million instances of
`org.netbeans.modules.csl.spi.DefaultError`, as well as 56 million
`java.lang.String`s.
