APAR status

  • Closed as program error.

Error description

  • Over time, Javascript scripts are added to the
com.lombardisoftware.core.script.js.ScriptCache class. When
numerous Javascript scripts are cached in ScriptCache class, the
 garbage collection longer to process and the CPU usage spikes
to 100%, possibly causing an java.lang.OutOfMemoryError.

For example, analyzing a heap dump shows that the script cache
grew to 5gb containing over 524,000 scripts:

com.lombardisoftware.core.script.js.ScriptCache @ 0x12bd87738|
24 | 5,311,589,336
