PH01455: PERFORMANCE DEGRADATION WHEN OPENING/EDITING [LARGE] JAVASCRIPT FILE IN RAD 9.6.X

Rational Application Developer for WebSphere Software Fix Pack (9.6.1.2) for 9.6.1

APAR status

• Closed as program error.

Error description

• You may observe a performance issue in RAD 9.6.x when attempting
  to open or edit JavaScript files, particularly .js files that
  are fairly large (i.e 100k+ lines of code). Note the same issue
  was not observed in previous versions of RAD (i.e 9.5.x, 9.1.x)
  and you would not see the same performance issue when copying
  the same code/text to a simple text file in RAD 9.6.x.
  
  The issue is caused by the version of JSDT (2.0) included in
  Eclipse Neon, which RAD 9.6.x is based upon. This version of
  JSDT uses Esprima as a JavaScript parser via Nashorn, a
  JavaScript engine; this combination of parser/engine causes the
  performance degradation observed, and has since been removed in
  Eclipse Neon.2. For more details, you may reference the
  following Eclipse Bugzilla:
  https://bugs.eclipse.org/bugs/show_bug.cgi?id=513464.
  

Local fix

• Please contact RAD support for a test fix.
